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.

  • What would cause a 4l65e transmission to, while traveling down the highway, all of a sudden jump out of drive? 1st gear is great, 2nd gear starts good, but then it starts a grinding noise until my speed reaches 25-30. Then the grinding noise stops as I shift into 3rd gear at 40 mph. It drives fine until I go back down to 40, then it slips out of gear. There is no 4th (drive) at all; I can only manually shift.

    It sounds to me like you have some internal problems with your transmission, and it will probably need to be disassembled to find the cause.

  • I have a 5.2 liter, Dodge 1500 truck. I took the pan off and cleaned the valve body. I also adjusted the bands. Now, when I take off, it doesn't slip, but at about 20 miles an hour it locks up the rear tires. What's causing that?

    I think you adjusted the bands incorrectly. I recommend consulting a transmission expert, someone who knows Dodge transmissions. It sounds like you're pretty mechanically inclined, so if you pick the transmission expert's brain, they should be able to get you rolling again.

  • I have a 2004 Honda Pilot with 262,000 miles on it. For the past four years, maybe once or twice a season it would slip out of drive after a stop. It either shifted to 2nd gear, or turn off. Restarting the car would remedy the problem, and then it would not happen again for weeks or months. This past year, it happened a few times, and then not for days. Lately, it's happened quite often until I had my power steering pump replaced. Since then, it has happened only once or twice. Does this make any sense?

    It sounds like you may have an electronic solenoid failing. If the check engine light is on or the "D" light is flashing, have the codes read, it will point you to which solenoid is failing.

      Hi Alyssa,

      I recommend you start with the obvious, if there's a problem with the shift cable, replace that first and see if you still have the problem. It is possible your vehicle was not in gear completely and it slipped out because of the cable. Let me know what happens, thanks.

      Hi. I have a 2008 Mazda 6 with an automatic transmission. Today, it felt as if my car had slipped into neutral on its own, because I wasn’t able to move too fast and the engine would rev but there was no acceleration. The only way to get it back to normal was by turning the car off and back on again. However I’m still worried. I bought the car used and I know that I have to replace the shifter cable, but I haven’t gotten around to it. Could the slipping be due to the shifter cable finally wearing out? Or a bigger issue with the transmission?

      Hi James,

      I recommend you check the connector (inspect it for corrosion) at the speed sensor if that looks ok inspect the wire harness from the sensor to the PCM for any rodent damage if no problems are found, check the wires for continuity from the sensor to the PCM.

      Hi Raine,

      When the transmission fluid sits for long periods of time like yours it tends to become gummy and valves stick. I don't usually recommend using cleaning agents in any automotive drivetrains but you have nothing to lose with this problem. Try using SeaFoam transmission conditioner, it may help loosen up the sticking parts. Let me know how you make out, thanks.

      I have a Toyota Corolla 2007 LE. I bought it new in September 2006. So the car is 13 years old with 166K. transmission fluid and filter change every 45K. Starting a month ago, I noticed transmission slip once a week. The first time it happened I did not know what it was. I had never experienced a transmission slip. I thought it was some kind of downshifting.

      After I read your article today, I definitely identify it as transmission slip not downshifting. I went to the mechanic but he could not replicate the problem. it happens only once a week.

      What should I do now? wait for it to become worse? rebuild transmission now? Thanks, Linh.

      Hi Chris,

      I recommend you do a battery test and an alternator test to start to eliminate the most common problems. If all is ok, inspect the engine compartment for any signs of rodent housing or debris like acorns, nuts, grass nest, etc. Rodents like to chew wires and it's very common to find harnesses chewed causing all kinds of issues. Keep me posted on what you find, thanks.

      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 Gina,

      I recommend you start by fixing the EVAP canister leak first and then clear all codes to see if any of the transmission codes come back. Keep me posted on what you decide to do and what you find out, thanks.

      I have a 2008 chevy Silverado. while sitting to either turn usually to the left, my truck suddenly makes a grinding noise, a clunk and then it wont move until I put it in neutral and the griding noise stops and then I can put it back in gear and it is fine. sometimes this takes a couple of times putting it in neutral. sound transmission to you

      Yes Eddie, the check engine light is on.

      I also went by Auto Zone last night and they added transmission fluid, and did a scan, they said it mentioned an "Evaporative Emissions Purge Solenoid"

      On another scan done by my friend prior to Auto Zone the following codes were:

      p1705

      Tranaxle control Module A/T Gear position Switch Circuit short

      p0700 Transmission control system

      p1457 EVAP control system leak detected (canister area)

      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 Gina,

      Is the check engine light on? It may not be a transmission issue, it could possibly be an engine skip or misfire, they feel very similar. Let me know if the check engine light is on, thanks.

      Hi Deanna,

      The first step is to identify what is leaking, once you have the leak fixed the transmission will stop slipping. The transmission is slipping because the fluid is low. Keep me posted on what you find, thanks.

      Hi, I have a 2006 New beetle Bug 2.4 automatic. It's started to slip on 1st and 2nd gear then the RPM shoots up and goes back down and I am leaking fluid that looks redish dark. I am hoping i just have to put more transmission fluid but the leaking do sent sound good. Any advice very much appreciated. 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.

      Hi Rob,

      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 Garry,

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

      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.

      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?
