Manual transmission problems can develop due to high mileage, abuse, or lack of proper maintenance. But they are rather rare. Most manual transmission issues originate not with the transmission itself, but from related components like the clutch assembly, linkage, or driveline: the components that transmit turning power from the transmission to the wheels. Also, as we discuss below, symptoms that seem to be coming from the transmission can come from unrelated parts of the car.
The key to diagnosing your manual transmission problem is to gather detailed information about the particular problem. For example, does the problem appear in only one of the gears, only at a certain speed, only when turning, only when downshifting, or after having serviced the clutch or another transmission component? Can you feel a vibration? Can you hear a clunking or grinding noise?
Symptoms of a Bad Transmission
Here are some symptoms that can indicate a worn-out transmission, each one of which we discuss below.
- Odd sounds (whirring, squealing, bumping, or thumping)
- Grinding noise
- Transmission jumps out of gear (into neutral)
- Difficulty shifting gears
- Car stuck in one gear
- Car that can't get into gear
- Leaking transmission oil
This guide will get you started on identifying the source of these problems. You'll need to investigate further and remember that manual transmission configurations can change from one model to the next.
Remember that this guide only deals with symptoms coming from the manual transmission (or transaxle) itself. Some symptoms that may appear to originate in the transmission actually come from the clutch (or another system), and vice versa. To get a more accurate diagnosis, take a look at the Bad Clutch Symptoms guide as well.
1. Odd Noises That May Come From the Transmission
The most common cause of a noisy transmission is insufficient oil, causing the gears or internal assembly to hum or whir. If a noisy transmission does have enough oil, the lubricant may be contaminated with metal shavings or particles.
Insufficient or contaminated oil may cause the transmission to become noisy in some or all of the gears. But if you hear noises in a specific gear, that gear's teeth or synchronizer may be worn or damaged.
Sources inside the transmission that can cause noise:
- A worn-out synchronizer
- The gears on the speedometer drive
- Misaligned transmission
- Flywheel pilot bearing
- A worn or damaged input shaft bearing, if your transmission makes noises only in neutral (sometimes a bumping sound)
- Worn-out gears
- Reverse idler gear
- Output shaft pilot bearing problems
- Metal shavings in the oil
Sources outside the transmission that can cause noise:
Some noises that seem to come from the transmission are actually coming from an outside though possibly related source. For example, if you hear a thumping noise when you accelerate or decelerate, check first for these problems before you blame the transmission:
- A loose or damaged engine or transmission mount
- A worn or damaged drive axle inner CV joint
- Problems with the differential case
Noises that manifest when turning could point to a problem with the CV joint. Knocking noises when driving at low speeds could come from the differential case or the CV joint. However, a worn bearing can also produce a knocking or thumping noise.
A Three-Step Test for Transmission Bearing Noises
That noise you keep hearing may come from a bearing. This three-step test is simple and can reveal problems with one or more transmission bearings.
- Fire up the engine and set the transmission to neutral. If you can hear a noise in neutral, suspect a worn-out input shaft bearing. Watch the video at the bottom of this article to see how internal problems can affect input shaft operation.
- Now, with the engine running, depress the clutch pedal just enough to remove the free play, to the point where you feel you need to apply force to the pedal to push it down further. You may need to push the pedal a little more. If you hear a squealing noise, you may have a worn out release bearing.
- Fully depress the clutch pedal to release the clutch. If you hear a whirring sound then, you probably are dealing with a bad pilot bearing.
2. The Transmission Makes a Grinding Noise
Problems with the transmission can also be revealed through a grinding noise.
A grinding noise may come from clashing gears. The clashing may happen because of worn or damaged gears, linkage problems due to wear or need of adjustment.
Other potential sources could be a worn or damaged synchronizer, shift fork, or rail and bearing shafts.
If you can hear the gears clashing only when downshifting, the problem may come from the synchronizer (too much play at the output shaft end).
However, a grinding noise may also come from a dragging clutch.
3. The Transmission Jumps Into Neutral
This seems to be a common problem on worn-out transmissions. You shift into gear, and the transmission jumps out of gear.

Once again, there could be other several causes for this problem, besides a worn-out transmission:
- A common problem is a worn out, stretched, or maladjusted shift linkage. A stretched linkage can be caused by a damaged engine or transmission mount. An external linkage can wear out or become loose and maladjusted, causing the transmission to jump out of gear. Look for rust and binding. You can try to adjust the linkage. But in most cases, you'll have to rebuild or replace that part of the assembly.
- You may be dealing with a weak or broken spring in the shift rail. In an internal shift linkage, the spring is part of the spring-loaded ball that locks the transmission into gear (detent). If the ball slips out of the notch, the transmission will jump out of gear.
- Also, you may be dealing with a worn-out pilot bearing (the gap causes the input shaft to vibrate, which causes the shift forks or synchronizers to move).
- You may have problems with a worn synchronizer or shift fork assembly or other internal components.
Other potential causes to keep in mind:
- Loose or misaligned transmission (possibly after service)
- Misaligned clutch housing
- Loose shifter cover
- Worn-out gear teeth
Note: When the transmission only jumps out of a high gear, check the clutch housing bolts for tightness, or the transmission for misalignment.
4. It's Hard to Shift Gears
This problem happens when you find it hard to move the shift lever from one gear to another. Usually, this points to a problem with a loose linkage, worn shift cables or worn bearings.
Pay attention to this: If you find it hard to change gears even with the engine not running, take a look at the linkage. If hard shifting only occurs when engine is running, check the clutch. If the transmission has been moved recently, check for misalignment.
Also, depending on your particular model, check the clutch hydraulic system and make sure it has no air. Check clutch adjustment as well.
Check the linkage. You may need to raise the vehicle and safely support it on jack stands or remove a component in order to make the inspection, depending on your vehicle model. You may need to remove a shift lever boot.
Get the help of an assistant to operate the linkage while you inspect the linkage, if necessary. Look for problems like binding, poor lubrication, misaligned components.
To remove components for inspection, consult your vehicle repair manual. Haynes is a good aftermarket manual: get the manual for your exact model.
Other causes for a hard-to-shift manual transmission include:
- Worn or loose internal components (shift fork, levers, shafts)
- Low oil level (or the wrong type of oil)
- Slipping clutch
- Misaligned transmission
- Failed pilot bearing or bushing
- Synchronizer problems
- Too much end play in the input shaft or main shaft
5. The Transmission Is Stuck in Gear
You may find that you can't get the transmission out of gear. This symptom may indicate:
- Low oil level or the wrong type of oil
- Problems with the linkage or shifter assembly. Look for maladjustment, or wear or damage to rods, bushings, or shifter arms.
- Internal components: shift rail, detents, forks or a stuck synchronizer sleeve
- Worn-out or broken drive gear teeth
- A stuck shift rail
- Misaligned transmission
6. The Transmission Won't Get Into Gear
When you have trouble getting the transmission into gear, inspect the shift linkage for adjustment, looseness or damage.
However, remember that failure to get into gear can also be caused by the clutch, if the clutch isn't fully releasing or has other problems. The clutch might need adjustment. Check my article on bad clutches. Also, consult your vehicle repair manual.
7. Leak From the Transmission
Manual transmission leaks can be caused by:
- bad or worn-out seals or gaskets,
- a damaged case or component,
- or even loose bolts.
To verify that a leak exists, first, check the transmission case and oil level. If it leaks after you just replaced the oil, you may have put too much. Consult your vehicle repair manual.
Locate the source of the leak. Inspect the transmission oil seal and the O-ring in the vehicle speed sensor.
Consult your vehicle repair manual for the proper procedure to replace seals, bearings, or gaskets. Some of these repairs don't require much work, and you may be able to do the job in your own garage with a few common tools.
Knowing about common manual transmission problems can help you diagnose your problems sooner, and possibly save money. This guide helps you identify and explore those common and not-so-common areas. Still, manual transmissions vary between models, so once you have an idea of the possible problem with your transmission, consult your model's vehicle repair manual to troubleshoot that particular issue. You may be able, in some cases, to do the repair yourself.
Also, keep in mind that it's not uncommon for some transmissions to suffer from design issues, like those in some 2012-2015 Mazda3, 2014-2015 Mazda6, and 2013-2015 CX-5 models with hard to shift or jumping out of gear problems. If necessary, check online for possible recalls or technical service bulletins (TBS) for your specific model or call your local dealer.

Questions & Answers
Question: Is the transmission blown if it acts like it's in Neutral even when it's in gear?
Answer: Not necessarily. Probably the clutch is not engaging. The clutch may be worn out, clutch in need of adjustment. or some wear on another component.
Question: I have a 2004 GMC 2500 Duramax diesel with a six speed manual transmission. Lately, when I try and shift gears, the transmission sticks or releases but I then can't shift. When this occurs, I turn the engine off and then upon restart I can shift again. This occurs at random and intermittently. Would this be a shift assembly or electrical issue?
Answer: My guess, there could be a problem with the clutch/slave cylinder assembly.
Question: I have a VW T25 diesel 4 speed. It started grinding into 3rd and 4th recently and can be hard to get into first. And pops out of 2nd. So not a good start (was fine before an engine replacement). I was driving on a trip, and it dropped from 4th to 2nd without touching the stick. Now I've only got reverse, 1st, and 3rd, and I'm pretty sure 2nd is 4th! Grinding when the clutch is engaged too. Any ideas? I've restored the linkage but no good.
Answer: It seems like an internal problem, probably a damaged gear. You may need to bring the car to a transmission shop for a proper diagnosis.
Question: I have a 2010 Honda Civic. Sometimes I can't shift up or down into 2nd gear. Usually, it'll engage if I come off and depress the clutch down again (sometimes just goes into gear if I hold the stick into 2nd for a few seconds). It's really random. Had 1st gear lockout for a while too but that problem left on its own as this 2nd gear problem started occurring. Linkage is tight. I'm told it's the clutch but only 2nd gear is affected (makes me think gearbox). What do you think?
Answer: Check the linkage; something that might be hindering movement to one side. Perhaps a bad bushing. This could be an internal linkage problem as well.
Question: I have a 2004 Jeep Wrangler SE, 2.4L with the 5-speed manual. My trans knocks but only for a very brief time after I turn the car on. It doesn't knock when I drive, and it shifts fine. But knocks when I turn it on and sometimes after I turn it off. What would cause this?
Answer: Knocking or clicking noises usually happen with worn gears, but this could also come from low fluid level. Sometimes it's a good idea to check the condition of the fluid. If you see metal chips, they may come from broken teeth. In this case, is better to remove as much of the fragments to prevent damage to other parts of the transmission.
Question: I have a 98 Dodge Ram 1500 4x4 nv3500. Trans grinds into 2nd and 3rd. If I pause after pressing in the clutch, it doesn't grind. Pedal seems a bit harder to press than normal. I changed the fluid. It was not too dark but magnet had a fair amount of metal on it, looked silver for the most part. Should I do a clutch before condemning synchros?
Answer: It does sound like a syncro issue, but it could be a linkage adjustment problem or slave cylinder issue as well.
Question: I have a 2007 Toyota Corolla that is making a whining noise in all gears and sometimes a clanking sound. Does this sound like it could be a problem with the clutch?
Answer: Seems like a worn clutch or flywheel; possibly a problem with the pilot bushing being worn as well.
Question: I have a 2012 Chevy Sonic with a manual transmission. It makes a knocking noise in all 5 gears that gets faster with speed. The noise disappears when the clutch is pressed, or when in neutral. What would cause this?
Answer: This kind of rhythmic, knocking sound usually happens in a component with a chipped or broken teeth. This may be a gear, input or intermediate shaft gears or similar part. But you need a good diagnostic, because something like this requires disassembly if a shop suspects this is what's going on.
Question: My 2003 Toyota Camry has a manual transmission. It grinds several times a day. It has popped out of gear one time. Is this something simple to fix, or will it be expensive?
Answer: First, make sure there's enough fluid. There could be one of several problems like wear or damage to bearings, gear or synchronizer. A bad synchronizer will make it pop out of gear. If you notice the noise is related to the pedal operation, the problem could be in the clutch assembly.
Question: What causes a vehicle to roll back an inch or two when you park on an incline and leave it in first? I once parked in second and the vehicle rolled back several feet.
Answer: If this was a slight incline and the vehicle started rolling, you may have a slipping transmission or an engine that's losing compression. However, even parking a car in gear in a steep incline, it may still roll. That’s why you always engage the emergency brakes and turn the wheels against the curb.
Question: I have a 2004 Pontiac Vibe. What would cause it not to go into 4th gear?
Answer: There are several problems that may cause this issue. Worn gear shift level, linkage or shift rail problems; bad synchronizer sleeve or hub.
Question: I have a 2015 Fiesta St and I’m having gear whine in 4th-6th. The dealer said it’s a synchro but that doesn’t sound right to me. I believe it has to be one of the bearings. Have any ideas?
Answer: This is usually caused by worn or damaged synchro, gear teeth or bearings.
Question: Transmission shifts fine to any gear and returns to neutral without any problem. That's good when the engine is not running. When the engine is running, then gear engages to any one gear, but will not disengage to neutral. No grinding noise at all. What could be the problem?
Answer: Seems like the clutch is not able to disengage. First make sure you have enough fluid. Otherwise, you'll need to check the clutch mechanism (cable or hydraulic system). Hopefully, you won't need to drop the transmission.
Question: 2013 Mini Countryman R60 S with a transmission problem. The car runs perfectly fine. However, when you put it into 6th gear, around 65 mph (104.61 km/h) or higher (in the beginning of the power band), the shifter will slowly move forward with more throttle until it pops out into neutral. You can hold the shifter in 6th gear and it will stay. Replaced the clutch pad and pressure plate 50k miles ago. I had no issues until 4-5k miles ago. I suspect bad synchronizers but maybe I am wrong?
Answer: There could be a problem with the synchronizer but check if the shift linkage needs some adjustment as well.
Question: Have a BMWZ3. I thought the battery was dead. Jumped it and started the engine. In first gear, the car engine bumped over; the car leaped forward and then cut off. I tried 3 times. Put the car in neutral, jumped it, and it started. But then it would not shift out of neutral. It had a strong smell of burning rubber odor. Car won’t drive at all now. What do you think is wrong?
Answer: It seems like the clutch is binding. The clutch disc probably got stuck. The strong burning rubber smell is probably the clutch facing rubbing against the pressure plate and flywheel. This could happen for several reasons: problems in the clutch linkage, warped clutch disc or pressure plate, loose disc friction material, problems with the release lever, bad pedal adjustment, bad pilot bushing or bearing.
Question: I have 2007 Toyota FJ Cruiser and it has a manual transmission. It seems like the clutch is slipping from 1 to 6 gear and reverse and the RPM is too high. You think my clutch is worn out?
Answer: A slipping clutch may be caused by a worn clutch disc and a number of other issues. This other post may help you diagnose the problem:
Question: I have a Nissan Xterra 2004 manual transmission, and the clutch is not coming up as it's supposed to do. It is staying down and I have to use my feet to put it in the right position to change gears. What can be happening?
Answer: Check first the linkage, if it looks OK, check for leaks at the master and slave cylinder. Otherwise, there could be something wrong with the release assembly internally.
Question: My son's truck wouldn’t go in any gear. A month later, it wanted to drive in 3rd gear only. Yesterday, it would go in every gear but 3rd and 4th. What is going on with this truck?
Answer: The shift linkage could have a mechanical obstruction (something loose or in need of adjustment) that prevents a smooth change or full travel and interfering with the shift fork. The issue may be between the shifter and case; other times, the issue is internal. Also, check the transmission and motor mounts. If they are loose or damaged, it'll cause the engine and transmission to move independently and misalign, changing the adjusted length of the shift and clutch control cables. This affects clutch and gears engagement.
Question: My car has no gears. It began not going into 2nd. Then all bottom gears, 2nd, 4th and 6th; then all gears. Now the shifter just turns freely in circles. What could be the problem?
Answer: First check that there’s not a problem with the linkage. The shifter should be properly connected to it. Other possibility is an internal mechanical problem in the transmission.
Question: I think my manual transmission has a stuck shift rail. What are some things I can try to fix it? The car is in neutral, but the shift looks like it's just about in first but not quite. The shifter is also pretty stuck on there.
Answer: You might want to check the gearshift linkages and check for some binding in the mechanism outside the transmission. Follow the gearshift level mechanism to the shifter assembly or rods, and see if anything is interfering with movement.
Question: My 2011 manual Toyota Yaris makes a grinding and scraping noise when I let off the accelerator while it's still in gear disappears when I engage clutch or accelerate. What could this be?
Answer: There could be a problem with the clutch release bearing. They sound like this when they start going bad.
Question: My 2003 Toyota Corolla will reverse with no problem or noise. I can shift it into first with no problem. However, when driving in first it shakes and grinds terribly. I have only crept along with in going 5mph to see if it would go forward; it does. Could this be the gearbox?
Answer: It could be a problem with the gearbox, input shaft or CV joint.
Question: I have a 1999 Toyota 4Runner Manual Transmission 5 speed. I am having trouble getting the car into 1st gear and reverse. If the car is turned off it will go into 1st gear or reverse no problem. Once I am driving the others gears seem to work fine with an occasional slight difficulty getting into other gears. I do not have any leaks or noises. Do you think I just need to change the transmission fluid?
Answer: Check the engine and transmission motor mounts. They could be cracked or worn.
Question: I have a 2008 Cobalt Sport. The shifter is loose and can rotate 360 degrees. It won’t shift into 4th gear and when I try, it grinds bad. So I completely skip that gear and go from 3rd to 5th gear. What could be the problem?
Answer: Most likely the shifter is either worn or damaged, that would prevent going into 4th.
Question: What would cause my 2001 Trans Am not to go into first with the car on or off? All other gears work.
Answer: The problem could be a detent plunger worn or broken spring or a loose plug (not able to hold the detent pin or spring). This is just an idea. You need a better diagnostic before disassembling.
This may give you an idea although the mechanism might not be exactly like yours:
Question: I heard a little bang when in gear, then I was out of gear, and although the clutch was able to put the tranny into each gear, the transmission would keep acting as if I was in neutral. Is this a clutch or transmission output shaft problem?
Answer: If there's enough oil, check the clutch linkage for adjustment.
Question: So when I let off of the gas of my car (but still in gear) at highway speeds (50 mph plus) there's a thumping and bumping noise. I can feel it very slightly! My question is, what would cause this? I have no other issues with shifting. I just noticed it happening today.
Answer: Usually, this type of noise comes from a worn universal joint; but other related issues that may cause noises during deceleration or even acceleration - axle bearings, or a worn transmission extension housing bushing.
Question: I have a 1926 Dodge with 3-speed manual gearbox floor shift. I can change up through the gears, but when I want to change down from 3rd (top) to second, I cannot get it out of top gear. The lever is stuck. Clutch works ok. Do you have any advice?
Answer: Make sure the shift linkage is not stuck, worn or damage. Otherwise, an internal mechanical problem seems to be the issue.
Question: 1992 Ford Ranger 5 speed manual. While running in neutral, as I let out on the clutch, it starts making a rattling noise. When I push the clutch in, it stops. Also it will go in all gears fine but when I start to take off, it will try to move but then makes a loud popping sound and won't move. Previous to this it had started making a whining sound when driving. What could be wrong?
Answer: This could be a problem of worn or bad countershaft bearings. But I believe your model has the Mazda M5OD R1 5 speed transmission. Make sure you got enough oil. The rubber shift cover plugs tend to shrink and leak, usually while the vehicle is moving. This could affect bearings and gears.
Question: I have a 06 Scion. In first and second gear only you can literally feel the entire gear shift pull forward when accelerating. In second gear, it pulls so hard it drops to gear shift back into neutral. If I try to hold the gear shift in second, it grinds. Third, fourth and fifth are all fine. Do I need a new transmission?
Answer: There could be a number of things. Gearshift, shift fork or rail problems, clutch shaft or synchronizer assembly damage.
Question: When I push on the accelerator and shift into gear, it makes a whiring sound when I drive. What could be the problem?
Answer: If you can hear the noise in all gears while moving, but you don't hear it in neutral, probably you got faulty output bearings.
Question: Sometimes when I shift my 1999 f250, it feels like it goes in gear, but the check engine light comes on, and there is no throttle response or grinding when I let out the clutch. I try to go into different gears, and this usually works. It was doing it a little bit, and I changed the clutch. It worked great for a moment, then started doing the shift thing again and feels like it is getting worse. There is new fluid in the transmission and filled until it came out the side. Could it be a bad slave cylinder?
Answer: It's hard to say without a diagnostic, but check the shift linkage for adjustment. Before you do that, though, make sure to download the trouble codes from the computer memory. They can point you in the right direction if there is any store in there.
Question: I have a Nissan X-Trail 2015, manual 4x4. When reversing on a steep uphill road the gear pops out! What could the problem be?
Answer: There could be a problem with the synchro, but you'll need a good diagnostic from a shop.
Question: My 2009 Mitsubishi Lancer pops out of first gear half the time and grinds when downshifting to 2nd, what could be the problem?
Answer: Probably the gearshift mechanism is faulty. Usually, this is caused by worn or damaged detent plugs or springs failing to keep the gear locked in place. Other problems that can cause the gear to slip: faulty shift forks or rail; a worn clutch shaft or roller bearing; worn pilot bushing; bad synchronizer assembly.
Question: My Ford F150 is stuck in second gear, but the shifter moves. What could be the problem?
Answer: The gearshift lever may be worn or broken, or there could be issues with gear train components.
Question: My 2011 Camaro is a V6 manual transmission but when the engine is running it will not shift into first. But, if started in first the car creeps forward; I've been using second for now. What could the issue be?
Answer: This could be several things, cable in need of adjustment, leaking cylinder (hydraulic models), a linkage problem.
Question: I have a 1998 Pontiac Firebird 3.6L V6 with a 5-speed manual Transmission. When shifting into 5th gear, it doesn't go into gear unless I shake it in and out. It doesn't kick me into neutral or grind unless I let off the clutch when it isn't in a while holding it in 5th without "setting" all the way in 5th. But it works fine as do the other gears; it just requires a little shake to get into gear. What could be the problem?
Answer: This could be a worn synchronizer sleeve or hub issue. But it’s better to get a proper diagnostic.
Question: 2005 Scion xB – car making grinding/banging noises while driving that caused the car to stop. The car seemed to be stuck in gear/gearbox scrambled. I was able to put the car in reverse with the engine running, and while trying to reverse the car made the same grinding/banging noises once I let off the clutch. After much resistance and noise, the car reversed like normal, and when put in first gear, it drove normal. What could be the issue?
Answer: It’s possible the front or rear bearing on the intermediate shaft is worn or damaged. But you need to have the issue correctly diagnosed before making any repair decision.
Question: Why has my 99 Nissan Frontier lost 4th gear?
Answer: There could be several reasons for this, like a damaged synchronizer sleeves or hubs; a worn gearshift lever; a problem with the shift rail or internal linkage; or a worn shift rail detent plunger (something like this: https://www.youtube.com/watch?v=H48OY-QYYSU).
Question: I have a 1999 Saturn SC1 5sp. I have trouble engaging the first and second gears, especially when the transmission is cold. What could be causing this?
Answer: Usually, incorrect grade gear oil would cause this kind of problem. But there could also be an issue with the gear linkage being out of adjustment.
Question: I can switch gears, and it won't take off. When I press the pedal in, all you can hear is a rubbing noise as if the clutch itself isn't catching and spinning around. What do you think it could be?
Answer: The clutch might be slipping. Set the parking brake, disengage the clutch, shift into third gear and increase engine speed to about 2000 rpm. Slowly release the clutch pedal until the clutch engages. The engine should stall. If not, the clutch is slipping. The clutch linkage could be binding, clutch disc wear, or some other damage.
Question: I have a 1989 Toyota with 5-speed Transmission that won’t go into 5th or Reverse. Does This Camry have a repair kit for The early 90s pickup do? At the shift linkage inside the car?
Answer: Check the motor and transmission mounts too. If you know for sure the linkage is the problem, search on line for the kit to get an idea about costs and what's included with the kit.
Question: I have Kia Pride LX sedan transmission problem. 1st gear is jumping into neutral. What is the problem? The 2nd and 5 gear are good.
Answer: There could be varied reasons for a gear to jump out. Most common: misadjusted shift linkage; shift rail detent worn (or spring); worn synchronizer clutch sleeve teeth; worn gear teeth.
Question: What would be the cause? I was driving my 2004 Jeep Wrangler today when I pushed in the clutch to shift gear, I heard a weird noise, then a clang. It slipped into neutral and would not go back into gear, and a weird pinging noise while sitting in neutral at idle. It started kind of whining last week when I would push in the clutch to change gears. Any ideas?
Answer: Seems like the noise was coming from low fluid. If heat built up enough, it might've caused gears damaged. Check first how much fluid the transmission has. If you hear some grinding when trying to shift into gear, probably the transmission is damaged. But you need a proper diagnostic before deciding on any major repairs. Also, there could be a mechanical problem in the clutch assembly.
Question: I have a BMW with manual gearbox Getrag GS6-17BG with 102.000 Km. When I put on the 1st gear and I'm taking out the clutch, the gear jumps to neutral. I have to accelerate a little more so that the gear doesn't jump. When the car is running I have no problems. What could be the problem with my manual BMW's gearshift?
Answer: There are a number of things that can cause this problem. Usually, shift lever and internal gearshift linkage problems. But worn out bearings can also cause a jump. Other sources include internal issues with the clutch pilot bearing, shift forks, and rails.
Question: What is the possible source of “ tapping” sound coming from a 2005 manual 6speed Jeep. I only seem to hear it in 1st and 2nd gear?
Answer: If the sound is coming from the transmission, this could be worn gear teeth. Unless there's some broken part (rhythmical knocking sound type) inside from chipped or broken teeth.
Question: I replaced the clutch in my 2003 Dodge Ram 2400. It has a six-speed manual transmission. Now, it grinds when I try to get it into third gear. While I was driving in sixth gear, it made a popping noise and felt like it was dragging from the bottom of the truck and the transmission fluid leaked out. I ended up having the transmission replaced completely. What did the guy who replaced my clutch do to it to cause all this?
Answer: It's hard to tell, but I assume it was a bad clutch repair job. Maybe the clutch wasn't adjusted properly, or the clutch began to bind. The fault could be in the linkage as well.
Question: I have a 2003 Honda Accord (Euro) CL9. My transmission grinds when I put it in reverse. I found out that before engaging reverse if I engage the 3rd gear and then the reverse, the reverse it won't grind. Sometimes it's hard to engage the 1st gear whether it's cold or hot. What should I do? Can the transmission fluid be the culprit ?
Answer: The clutch might be dragging. Shifting into a higher gear before engaging reverse helps to stop reverse from spinning. Usually this happens because the clutch is dragging. The clutch disc is spinning and then you hear it grinding. Most of the time first and reverse don't use a synchronizer. If first has a synchro, the selector ring and blocker ring have problems (wear-damage) aligning. Check the hydraulic system for leaks or problems with the master and slave. This other post may help as well:
Question: There is a clunking noise coming from the right side axle. And when I jack up the car, put it in gear with the motor running only the left wheel turns. What could be the problem?
Answer: The CV joint (the part of the axle that slides into the splined hub on the wheel) is probably busted.
Question: 1988 Ford F250, T18 4 speed. Shifts perfect when ignition off, when on it will not go into any gear. I have replaced clutch and clutch master cylinder. What is causing lockout?
Answer: There could be a problem with the clutch assembly. You may need to check the clutch disk and pressure plate.
