The Most Common Reasons Why a Transmission Slips

Updated on January 27, 2019

Eddie spent 35 years in the automotive business with Honda. He is an ASE Certified Master Technician and has bruised knuckles to prove it.

We all know what an automatic transmission is, basically—very basically, at least—so I'm not going to bore you with the details about how it converts power from your engine into power at the wheels. But you should know that the process involves plenty of hydraulic fluid as well as gears and clutches.

If you don't know why your car’s transmission is slipping, I just might have the answer, though you may not want to hear what I have to say.

The cause of a slipping transmission will depend on the type of transmission you have in your vehicle. There are three types of transmissions: automatic, standard (or “manual”), and CVT (continuously variable transmission). I will discuss the two most common types, automatic and standard.

Why Is My Automatic Transmission Slipping?

If you have an automatic transmission and it "slips" while you are driving it—that is, the car engine revs without the power going to the wheels—the most common cause (though not the only possible cause) is low transmission fluid. If the slipping is caused by low fluid, it will get worse as the transmission gets hotter.

Why Is My Manual Transmission Slipping?

A standard (“manual”) transmission uses fluid too, but leaks aren’t a common issue; a standard transmission could lose all its fluid and never slip at all, though eventually, it would lock up while driving down the road. If you have a standard transmission, and it’s slipping—the engine revs but it doesn’t transmit power to the wheels—the problem is usually in the clutch.

Further down in the article, I discuss how to diagnose this problem.

Sounds Like Low Transmission Fluid to Me

What to Do If Your Automatic Transmission Is Low on Fluid

The next question is, why? Probably because you have a leak. Maybe you have noticed red transmission fluid in your driveway or your parking spot at work, but it didn’t occur to you that it came from your car. The cause of your leak is probably a failure of one of the seals that keep the oil inside the transmission (though there are other places the transmission might leak). How many seals the transmission has depends on whether you have a front-wheel-drive, four-wheel-drive, or rear-wheel-drive car.

If you do have a seal that is leaking, and you catch it in time before it damages your transmission, there’s a chance it might be relatively cheap to repair. Seals themselves are not expensive parts, but depending on where they are located, it might take a lot of labor to replace them.

If you have the leak checked out by your mechanic, and he tells you it’s just your axle seal, it could just cost you for a couple hours of labor, and you could be back on the road in a few hours if the parts are readily available. Axle seal failures are common, and the dealer will usually have those seals in stock. But if it's your input shaft seal, plan on leaving your car for a day or two, and expect the labor cost to be upwards of eight to ten hours.

Checking and Topping Off Automatic Transmission Fluid to Prevent Slipping

If your transmission is leaking, you will want to fix it. Meanwhile, if you must drive a car with a leaking transmission, you should top off the fluid.

Check your owner’s manual to see exactly how you should check your transmission fluid level. Some manufacturers will want you to check the transmission fluid level when the engine is warmed up and running with the transmission in park, other manufacturers like Honda will have you check it with the engine warmed up but not running. So be sure to read your owner's manual, DON'T GUESS!

If your transmission fluid level is low and not showing on the dipstick, add transmission fluid--the proper transmission fluid. Each car manufacturer uses a specific fluid. If you use the wrong fluid, you could damage your transmission internally, so again, check your owner's manual. Fill it to the top line on the dipstick and then drive it to your mechanic.

Note: Sometimes when an automatic transmission is low on fluid and you top it off, air pockets develop inside the transmission that keep the fluid from getting to all the parts of the mechanism. After adding the fluid, I suggest that while the car is running, you move the shift lever through the different gears on the shifter selector, and then check the fluid again. Running the shifter through the gears redirects the fluid to different parts of the transmission and removes the air pockets. You may have to do this procedure several times, or even drive the car around the block, and then recheck the fluid level.

Note: I do not recommend using additives that are supposed to stop leaks; they can plug up the transmission. Use the automatic transmission fluid your car manufacturer makes.

How to Check Your Transmission Fluid

Other Fluids That Leak From Cars

If you are concerned about other fluids besides automatic transmission fluid that seem to be coming out of your car, here's some useful advice.

Common Cause of Manual Transmission Slippage: Worn-Out Clutch

If you think your clutch is starting to slip, you can try a stall test. Put your car in third gear and try starting off like you would normally, as if you were in first gear. If your clutch is working properly, letting the clutch out all the way should stall the car. If, however, the clutch is slipping, the engine RPMs will rise, the car will slowly start rolling, and you will have a smell like burning paper coming from the engine compartment. When a clutch starts slipping you will smell it. It’s like the smell of overheated brakes.

There are many reasons why a clutch would slip, but the most common reason is that the clutch is worn out. A clutch disc can last anywhere from 20,000 to 200,000 miles—it all depends on the way you drive—but like a brake pad, it’s a consumable item, and will be used up eventually, leaving the parts grinding metal-on-metal. If the clutch disc is worn out, you need to replace it, generally also along with the clutch plate and one or two bearings. If you don't replace a worn clutch in time, you might have to replace the flywheel (the big chunk of metal next to it) as well.

Riding your clutch—that is, leaving your foot on the clutch pedal when you aren’t using it—can really eat up a clutch disc fast, especially if you drive in hilly areas. Just being a newbie and learning to use a clutch for the first time can cause a lot of wear and tear. Learning to drive on a standard transmission can end up costing you money if you don't get the hang of it quickly.

Then again, clutches slip for reasons not related to wear and tear or abuse. If your input shaft seal is leaking gear oil onto the clutch disc, this could very well cause a slipping clutch. Another common reason for a slipping clutch is a faulty or damaged pressure plate. The pressure plate is operated by a high-tension spring. If for some reason the pressure is not distributed evenly over the clutch disc, the clutch will start to slip.

Questions & Answers

  • I have a 2011 Chevy Silverado 2500 HD. This morning, as I was driving about 30 mph, the engine started to roar as if in neutral. It did this about three times for about a mile until I could get home. I later drove around the neighborhood and it does seem to make a vibrating noise at times, and it also seems like it is shifting at times. The fluid level seems normal. It is a used vehicle that we purchased three months ago, so I know nothing about the history. What could this be?

    If the fluid level is OK, it's possible you may have a solenoid or valve that is sticking or not working properly.

  • I have 2012 Silverado, and the transmission slips while driving. If I stop and restart the engine, it drives fine. Do you have any idea what this could be?

    It sounds like something electronic, like a solenoid or valve, so it could be a quick fix.

  • While accelerating, my manual transmission seems to slip. Would that be the clutch or a deeper issue?

    On a manual transmission, the only way it can slip is from the clutch. If you start from a stop in second gear and the clutch doesn't grab the point and almost stalls the engine, then most likely, the clutch is on it's way out.

  • I've got an 83 Yamaha Maxim 750cc. It doesn't slip per say, but it pops out of first gear and back into neutral on its own. It only does this from first gear, and it happens more frequently as the engine warms up. What could cause it? I Haven't checked the clutch cable to see if it's loose, but the stall test is fine. I'm at a loss

    Usually, when a transmission pops out of gear it's because a shift fork is bent inside the transmission. The shift fork is what moves the synchro up and down the gear, and if it becomes bent for whatever reason, it will slip out of gear.

  • My 2008 Ford f150 like thumps a little when running 45 or so. It doesn't jerk or rev, it just feels like someone has a rope tied to the back and giving it a quick little tug. Is that my transmission?

    It could be but it sounds to me like maybe a bad spark plug, plug wire, coil or something to do with spark, it's just a hunch.

      Hi Marcus,

      It sounds like you have no main pressure. You could check the pick-up and o-ring in the transmission pan, it could either be clogged of loose, other than that it could be the pump or something else.

      I have a 2000 Jeep Cherokee. It was idling high, so I replaced the throttle position sensor. The idle air control valve is fairly new as well. Replacing the throttle position sensor fixed the idle problem. However, my Cherokee now revs really high and it feels like the transmission is slipping or disengaged until as it shifts. I have to take my foot off the gas and then press slowly for the transmission to reengage. Until I replaced the throttle position sensor, my Cherokee had never done this before. Help, please. Any ideas?

      Hi Ernesto, The vehicle should still be under factory warranty so I recommend you have it towed to the Dodge dealer closest to you. Also you may want to call them before towing it just to be sure it is under warranty. Sounds like the transmission pump has failed.

      Hi Eddie. My husband has a 2005 Buick Rendevouz where the automatic transmission slips when shifting between first and second gears. Is the transmission wiped out? Could it be the “solenoid “ in the transmission or something else not as egregious?

      Thank You, in advance, for your help. ☺️

      My 04 Honda civic sat for a long time due to a hood cable break. I had the transmission slip real bad after sitting at a long red light. Had the fluid changed but it did it again, this time not as bad. Both times I was on a slight incline. What could this be?

      I highly appreciate your educative words.

      Mine is a Mitsubishi Montero Sport - 2012 - Thailand - diesel - 105,000km.

      ATF changed at 80,000. 9.7 liters per Manual. No leaks appear.

      The dipstick is hopeless. It shows the oil level well above the maximum or actually the level is higher. No way for me to know.

      The jeep shifted to neutral recently, while driving at 50/60, but re-engaged after stop ( engine not stopped) and gear shift. This was repeated at two other subsequent drives.

      Hi Mike,

      That's really weird, it sounds like you're losing pressure to the first clutch. It's possible you have a sticking valve inside the valve body. If you have a transmission specialist near your home you could schedule a road test with the shop, they may be able to tell you the issue without diagnosing it. Keep me posted on what you decide to do, thanks.

      I have a 2011 GMC Yukon XL with a5.3 liter engine with113,000 miles. About a month ago thought transmission was slipping a little climbing hill getting on highway about 50mph. Got home went to check fluid and fill pipe came out with stick about 14” long .Not sure how long it has been broken. Last service was a oil change about 3 months ago Called dealer about it as they did a GM issued repair to prevent such damage in 2016. Stopped driving and towed to dealer . Advised not to drive in rain to dealer. Although we have had the rainiest 2 months in history the last two months. Dealer repaired pipe under previous work order and changed transmission fluid . Asked to check transmission as did not want any issues going forward as I did not know how long pipe was broken and what got in there or leaked out . Drove home 5 days later pulled out of driveway and would not go over 10mph. Towed back to dealer . Transmission gonzo. Says not related to broken pipe or fluid flush. Now Says there was no water in fluid but was very dirty and discolored. Never said anything at time of repair. Wants 4500 to replace transmission . Would appreciate any advice you can give me going forward . Thank you.

      Hi Kim,

      I think you're right, I think you may need a minor adjustment on the servo, it sounds like there may be too much or not enough pressure in the servo to cushion the shift. If you know of another transmission shop that is reputable, I highly recommend you get a second opinion. Keep me posted, thanks.

      Hi,

      I have a 2002 Honda Accord with a rebuilt transmission...

      I noticed that when I am on the highway, going into the 55-60mph range, the car starts to buck, then stops as I slow back down...

      It sometimes shifts roughly in lower gears as well, or so it feels...

      I am clueless and do not want a mechanic to take advantage of my ignorance. lol

      Could this be a transmission issue? even with a replacement? it was a used one for $650 the original owner said. Please advise.

      I have a 2007 4X4 Ford Ranger (186000 Km on it and I bought it new). The automatic Transmission fluid was leaking so I took it to the Tranny shop and they changed two Servo Caps and put in a new TR Sensor. Now when I put the truck in "Drive" it doesn't always go into gear right away and revs and then "bangs" into first gear. Once it is engaged it seems to shift normally through the other gears when on the highway. If I put it into 2nd instead of Drive when starting out, it seems to go into gear fine so not sure what is going on with it. They did something to the "shifting" mechanism as well and it seems rather loose to me. Took it back to the Tranny place and talked to them about it and they said I should tear the whole transmission apart and rebuild it but my intuition is saying they didn't do something properly and it is an easy fix and I don't think spending $3000.00 on a rebuilt transmission is necessary. My next option (which I will probably take) is to take it to another shop for a second opinion but came across your site so thought I would see what you had to say about it. Thanks.

      Hi Hudginsjp,

      Sorry to hear about the troubles you're having. It sounds like your clutch is slipping when it gets hot, it's the only reason for a standard transmission to slip. I recommend you have it replaced by a reputable shop. Let me know if you have more questions, thanks.

      I have a 1998 ford contour 5speed and a few days ago it slipped in 5th gear.

      I didnt know it was slipping until today.

      What it was doing was if while in 5th if i pressed the gas to accelerate too hard the rpms would shoot up really high but it didnt feel like it went to neutral because it was still accelerating just not like it should for the rpms. Not knowing what was happening i kepted on the gas and as it sped up the rpms came down and they met in the middle so at 45mph i hit the gas hard and the rpms went to 6k but but the car was eccelerating like i had only slightly pushed the gas but once i hit 55mph the rpms at 4.5k then at 65mph the rpms at 3.5 which is normal. This happened about 4 times over the last 2 or 3 days and i couldnt figure it out. Then today i drive it to visit my wife 30 min one way and everything is fine there and back. But a few hours latter i go to drive it again And it has very little acceleration... im thinking its out of gas and put half a tank in but when i go to leave the gas station i can not press the gas pedel more then a baby toe of pressure or the rpms shoot up and the car wont accelerate at all once the rpms go up and its now happening in all the gears. The rate of acceleration is about 0 to 60 in 5 minutes and im not exaggerating. Trust me everyone on the highway was letting me know as i was trying to get to speed to get home. I got the car to go 70mph wjth normal rpms by very very slowly accelerating but the car is not drivable like this. I just looked it up and read that its the clutch slipping and so i check the clutch as follows. Start car, place in 1st, pull handbrake, dump clutch with no gas and the car stalled right out. I tried this in 2nd gear as well and the car stalled out.

      Please help me, im currently homeless and living in this car and i need to be able to get to work or ill be homeless and carless and no way to fix either with out my job.

      After eating at Denny's you may have to .... never mind lol. If the trans only slipped once it may not even be the transmission you felt slipping. If it continues to happen I recommend having it checked out but I don't think you should be worried about it right now, but I would be worried about your choices of places to eat lol.

      Hi Dave,

      Are you sure it's no an engine skip or misfire? Another reader Joe just had a similar issue and he found deteriorated coils. I recommend you inspect for an engine skip/misfire first and let me know what you find, thanks.

      Hi Garry,

      I think you have an internal leak and once the transmission warms up the metal expands and temporarily fixes your issue.

      Hi Joe,

      That's great news! Sometimes a skip in the engine will seem like a transmission slip, the problems are very similar. I'm glad it all worked out, the coils and plugs are a lot less cash than a transmission lol. Thank you for coming back to post your findings, this really helps other readers with similar issues :)

      Hi Tom,

      I recommend you change the transmission fluid to see if the problem persists. It sounds to me like there is some debris clogging up one of the ports or solenoids. Is the check engine light on? If so, the computer has stored a transmission code and it just needs to be diagnosed.

      My honada while driving is reving out.

      I stop it turn off the car.

      After 15 seconds i start it again and its drive and change out nicely.

      But after a few miles up the road it start to rev again i repeat the process.

      My mechanic add a few bottles of oil and we test drive it same results so he said the transmission need to change.

      With your experience could this be something else?

      I change it a few year back rebuild it.

      Atlease so they say.

      What you think?

      First off, thank you so much for all your help. A misfire was the problem. I pulled the coils and they looked worse than the ones I replaced?! All but one was corroded and falling apart. The plugs did not look bad at all to me but just to sure I replaced them as well. I upped the quality on these parts and my car ran like a champ. I waited a few days to post to be sure but I am certain the issue has been resolved.

      I have a 1995 dodge ram 1500 1st gear slips in and out till it gets warm and then it shifts fine but the rest of the gears are good what would cause this a bad band or sylnoid. It had low fluid but its been sitting 9 hours not 1 deop of fluid yet has leaked so i dont think it would be a bad seal or leak in the lines anywhere?

      Eddie, My '03 Jeep Liberty 4WD 4 speed AT just developed an atypical (to me) slipping problem. Fluid looks great and I'll check the level today. No leaking evident. It has a very short period slip-like impulse maybe a second in duration. I can't tell for sure but it doesn't seem to be at a natural shift point, e.g. when going uphill and it may want to downshift. I can be on level roadway when it happens. It may be starting a shift sequence then stopping or a slip that ends abruptly. Ideas?

      Hi Joe,

      Yeah, it sounds like a misfire. I recommend you check all your plugs for cracks in the ceramic insulators, and if you dropped one during installation I highly recommend you pull that plug and check for cracks and also check the electrode gap.

      Hi Kim,

      I think the transmission is full. It's most likely slipping because of a different problem? Those codes are generic codes so I have no idea what they are, sorry. I recommend having someone with a good scanner pull the codes, you may just have a problem with a solenoid or valve.

      There are no lights coming on my dash board. As for a misfire, I did change out the plugs at the same time. So I can double check my connections and let you know what I find. The fluid I used was generic since it was to only option I had at the parts store. However it had the same ratings my trans required so I did not think much off it.

      Thank you

      Hi David,

      I'm not familiar with the Legend transmission but it sounds like a solenoid is sticking, maybe the 3-4 shift solenoid? Honda usually has the solenoids bolted on externally so they are easy to replace if there is a problem, hopefully, this is your style as well.

      Hi Amanda,

      Unfortunately, when cars sit for years the fluids get all gunked up. You could try having a transmission shop flush the fluid and replace the filter, it's a quick inexpensive check.

      Hi Allison,

      No leaks but is the fluid level correct and what is the condition? I have seen transmission coolers fail internally and mix the coolant with transmission fluid because the transmission cooler is at the bottom of the radiator. I'm not saying that is your problem but you need to check the fluid level and condition because of these types of problems.

      Hello Eddie,

      I drive 92 Honda Legend Coupe 4 spd automatic and its transmission has started to slip just recently. Sometimes, after driving for about a minute, the gears disengage, RPM rise to about 2000 and the only way to make the car move again is to bring it to a halt, select a Parking mode, then D4 and everything returns to normal. It has been happening only when cold, both in D4 and D3 modes. I had the whole transmission rebuilt a year ago (torque converter, internals, vehicle speed sensor have been changed, …); the fluid does not smell bad, nor there are any particles, fluid level is correct as well. There are no warning lights on the dashboard, no flashing lights either when the slipping occurs...

      After a consultation with other owners, we agreed that the culprit might be the mechatronic/hydraulic system (“the brain of the transmission” with all the solenoids, valves, springs...), but none of us were 100% sure :D. And since 2nd gen Legend was not officially sold in my country, the local dealership was not much of a help. Could you please help? Do you (or anybody on this forum) have experience with issue such as this? Thank you for your time :)

      I have a 2016 Chevy trax and I recently changed the fluid in my transmission instead of taking it to a mechanic as reccomended by the manual. There is no dip stick so I just added back the amount of fluid my trans is suppose to hold. Since then I’ve been experiencing symptoms similar to slipping but the rpms do not increase during these times. Instead it is more like a loss of power to the trans and feels like it is trying to grab the gear again. It does this in short bursts repeatedly at hwy speeds and more so when using the Cruze control. Any suggestions will be much approeciated. Thanks you

      Hi Blake,

      Most likely you have a blockage in the main clutch line and the transmission is starving for fluid. This happened to my kids 99 CR-V, I ended up using compressed air lightly in each one of the pressure ports on the transmission and it greatly reduced the problem. I also recommend a fluid change after you do this because you're moving debris inside the transmission. Let me know if you try this, thanks.

      Hi Kristina,

      This is the only way I know to prove your point to the dealer. Drop your car off the night before your appointment. Have someone drive you to the dealership in the morning, test drive the vehicle with either the Service Manager, Shop Foreman, or the Tech so you can point out the problem. I know it's a lot of extra time you probably don't have but it will prove to them your vehicle has a problem they need to fix. Keep me posted on what you decide to do, thanks.

      Hi. Just bought used 2017 Chevy Cruze. Dealer never told me engine was replaced at 17,000. Found out after purchase. Now has 50,000 miles. The transmission is slipping in 4th gear (only 4th). Hard shifted a few times but generally revs between the shift. Dealer kept it for 2 weeks & said it never did it for them (of course it didn't!). Now ive had it back and it does it daily. It's only first thing in the morning. Once the car has been moving for a few it seems to not do it. Any advise?

      Hi Joel,

      It sounds to me more like a sticking valve or solenoid but without a code, it will be hard to diagnose unless you can find an expert transmission tech who knows how to check the pressure while driving. The difficult part about diagnosing this problem is it happens under heavy acceleration, so unless they have a scan tool to monitor the transmission while driving, it will be a tough diagnosis.

      Thx for your expertise Eddie! 2005 BMW 330i - GM 5L40E transmission. Getting a slip or "flair" into 2nd gear, mostly only noticeable under heavy acceleration from stop or very slow speed and gunning it. Seems to get a bit worse when warmed up fully. Also had one instance of hitting accelerator hard to get around an issue on highway, dropped into 2nd to accelerate then wouldn't come out of 2nd for around 30 seconds no matter what I did, then eventually upshifted to 3rd/4th and I was on my way. No codes ever. I performed one fluid change according to BMW specs/directions - have seen no change in behavior. Just over 100K on the car. Valve body? Or truly a gear issue (I hope not - really don't have the money for a whole new transmission!).

      Thx, Joel

I thanked my car for not leaving me stranded on the highway, and went into work and had it towed home at the end of my shift. I guess i will look into replacing the Tranmission now.

      I' ve been send my car for repair, they suggested to change solenoid and transmision heat sensor, after changed this parts, problem remain.

      Then, they suggested to changed valve body assembly and new set of cable joining to gear box.

      Finally, the system error been solved. However they told me after the gear box heated temp increase, they still found this transmision shifting issue.
