Most Common Reasons Why a Transmission Slips

Updated on January 8, 2017

33 years in the automotive business, Honda, ASE certified master technician. Willing to spill my guts about everything I have learned.

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

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.

Input Shaft Seal: Another Site for Leaks

Be sure to check your owner's manual on how to check your transmission fluid.

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.

      Hi Phil,

      If the clutch is slipping, your vehicle will lose speed and the rpm's will rise at the same time you lose speed. I'm not sure about the turbo losing pressure, that would be a separate issue.

      Hi Danny,

      I recommend checking the fluid level and condition first. It sounds like you're losing pressure inside the transmission, this could be cause by either a clogged filter, broken o-ring, or faulty solenoid.

      Hi Ana,

      I highly recommend you take it back to the shop that did the repair, seems to me that they didn't fix your problem and you probably paid them a lot of money for the repair. I recommend you have them fix it at no charge now.

      Hi

      We own a Ford S Max 57 plate. It has done 152,000 and has been a great servant. We think the clutch is stating to slip which is our first clutch so not surprising. We just had it serviced and MOT and the garage said it was starting to slip but we also have a loss of power so we accelerate and there is a delay in speed picking up which is getting worse. It failed its emissions test so we had a terra clean service and that is now fine but has not resolved the power issue. However, the garage where we had the terra clean service done said "you know that loss of power you mentioned - well you have a slipping clutch" which they noticed when they took it for a test drive. To add further the garage that did the MOT said that diagnostics had picked up an issue with loss of turbo pressure but they couldn't find anything like a split hose or such. I am now in two minds as to whether to have the clutch replaced and see if that resolves the issue. Have you any recommendations?

      Hi, I'm ok with cars, better than my husband. The transmission starting slipping (automatic) and he took the car in. A few days later I asked where the car was and he said getting a new transmission (used), 75,000 miles 2010 dodge??? I asked why and he said that's what they did. I felt bad because everyone knows I'm better at the "guy" things than him. The car returned and when I drove it I immediately noticed it was not in gear .He took it back now it's running on 3 cylinders?? It's a new shop and I think we got an unnecessary transmission swap. Could it of been the cylinders from the beginning? Transmission fluid was flushed I believe a week or two prior but was already slipping. I should have taken over but I let him handle it. They have had our car for almost 3 weeks! Thanks

      When a transmission has a hard time going into gear or it pops out of gear, it's a sign of worn synchros or bent shift forks. Both of these parts are serviceable by removing and disassembling the transmission only. this is a job for a transmission shop. Hope this helps and sorry for the bad news.

After it warms up, it drives fine, unless a sudden hard brake, or, while raining and doing a U-turn. It has never slammed into a lower gear, only into neutral. Is there a solution other than rebuilding the trannie? Thanks!

      Hello. Yesterday morning I had the oil changed on my 2002 Honda Accord (manual trans). It's an old car and has 112K miles on it but has driven just fine until last night. I was in 5th gear on the interstate, heading up a hill and all of a sudden I lost significant power and my check engine light flashed three or four times and turned off. I downshifted to fourth and had no issues. Later that night I was in 3rd going about 40, again up a decent grade, and I started to hear a clicking sound (maybe gears slipping?), again lost power and had to downshift to 2nd. It wasn't perfect but it was way better than the power I had in 3rd. No check engine light that time though. I'm taking it in to the dealer tomorrow but am hoping for some advance insight if you are able to speculate. Thank you!

      Shifts ok but when up to speed and then I give it enough throttle to downshift, it just shifts out of gear and revs (or the gear it drops into is slipping?) Also shifts a bit late out of first if I am accelerating a little too hard. Also I have to put it in neutral and wait about 30 seconds before driving because I think the torque converter drains when sitting.

      Thoughts?

      Hi Rene,

      I recommend having one of the mechanics go for a ride so you can point out the problem. Have you checked the fluid level yet? That is a good starting point because when you on a hill, the fluid level is uneven, so if it's low, you could be losing pressure.

      Hi Ed,

      If you're looking to have someone crack open the transmission and replace parts, you may want to seek help at a transmission specialty shop like Aamco. My thought is if you going to remove the transmission and pay the labor to crack it open and replace parts, it's more cost effective to replace it with a reman with a warranty. It would almost be the same cost.

      I have a 2010 Mazda 3 automatic with intermittent slippage, ( over revs to 4k- 5k and lurches) only when starting on a hill. We are talking neighborhood speeds. Transmission has been flushed, TCM and Stability control module have been replaced and the problem returned twice at two weeks out of the shop. Spark plugs have been changed. What else could the dealer be missing? They haven't been able to replicate the problem.

      I have a 2008 Nissan Altima with a CVT. Had the fluid changed and the transmission seems to be slipping. I understand the CVT mechanics so my question is can you just change the primary clutch of a CVT or do you have to replace the whole thing? The Nissan dealership said we had to replace the whole thing but Im pretty sure they are just trying to get us for $3000+. It runs ok when its cold but once it gets warm it jumps or rather won't "shift" so what are ur thoughts? any info is appreciated

      Hi Oscar,

      I recommend having the vehicle checked first by a reputable mechanic or transmission specialist before you start guessing at what is wrong, you may spend money unnecessarily. Keep me posted on what you find, thanks.

      I have a Honda accord 2002 and yesterday I used a scanner to see what was wrong and the code p0700 came up also when I drove it the other day I always put it in third gear since it's automatic and when it's was trying to change gears the car shook a lot and then changed gears it also stop going I pressed on the gas and the only thing going up was the rpms and it was still on third gear I was thinking it might be the transmission solenoid since that hasn't been replaced yet at all transmission should still be good since it was rebuilt in 2010

      Hi Justin,

      I'm going to recommend bringing it to a transmission specialist. It's possible you could have bent something internally when you hit the shifter or there may be a problem in the valve body. I recommend double checking everything in the cab because it just seems like you may have bent something or dislodged something when you hit the shifter.

      Hi Patrick,

      Usually, when a transmission problem comes and goes like yours, it's caused by some electrical issue. Is the check engine light or any other warning lights on?

      I an 04 Grand Prix GT (4T65E Trans) the trans shifts fine and randomly starts shifting hard between gears especially in the city, but when I restart the car after letting it sit for 5-10min its stops hard shifting and comes back after more city driving. Now the new trick is this weird shuttering I'm getting on the fwy around 65-80mph. I checked the fluid and appears normal and lastly I get this weird (straining noise) when I'm in an enclosed space and hear the car. I'm running out of ideas and wanted to know if you guys might have an idea?

      Hi Justin,

      It sounds like your transmission cable is out of adjustment so when you have it in drive or any other gear, it's not in the correct gear. I recommend checking the shift cable from end to end to see if it has come out of one of it hold downs or brackets. Let me know what you find, thanks.

      Hi Jake,

      This is a tough one because your vehicle has a lot of miles on it and it's possible the transmission failure is a coincidence. Do you have proof they used the wrong transmission fluid? Once a transmission has an internal failure, the fluid can become burnt in an hour depending on what has failed. I recommend getting a second opinion from a transmission expert like an AAmco transmission shop or someone who specializes in transmission repairs, this will give you the proof to present to Jiffylube that they have caused the issue. Let me know what happens, thanks.

      Hi Eddie,

      Thank you for the replies. I will check with Mitsubishi.

      As you had indicated previously, it might be an internal leak, I will also check the local Authorized Mitsubishi service center's capability to fix that.

      Thank you.

      hey I have a 1987 Chevy s10 blazer 2.8 liter 4x4 that I took to jiffy lube to have fluids rotated and changed. atf being one of them, I drove my truck yesterday and had absolutely no problems, started her up today and she hard shifts into (reverse), then hard shifts into (Drive or Overdrive) but 2nd whines, and well as reverse. I suspect it to be the filter, which should have been replaced. you know better. oh plus she used to shift into 2nd at 15mph now she shifts only from 1st to 3rd at 40-45, strange enough the transmission will downshift into second. I have never had this problem until jiffy lube she turned 30 last month abd ran like a top and now I'm having problems vehicle has been properly maintained and has 267,000 miles on it, jiffy lube told me it's from my transfer case chain heating up and stretching, I did research on their claim, and from what I found that information is false, I believe they are trying to cover up that they damaged my transmission and dont want to pay for my transmission to be fixed due to they're negligence, I also know they used the wrong fluid because it's burnt 7 days after being replaced with new fresh atf. email me at Jacobmkiser@gmail.com put Chevy s10 in the subject so I can find it. I need your expertise.

      Hi Ron,

      The mass air flow sensor would cause your engine to run like crap and usually stall. It sounds like maybe they didn't have enough fluid in the transmission when you took it the first time and topped it off on your last visit. I'm not positive about the fluid, but I'm positive the mass air flow sensor was not your shifting problem.

      "Hi Vicky,

      It sounds like your transmission has an internal leak This could be caused by debris or a failed part inside the transmission. Are there any warning lights illuminated on the dash?"

      Hi, thanks for the reply. No warning lights at all. If I shift to D mode shortly after cold start, the gearbox engages with unhealthy jerk and starts rolling forward with hesitation. In 500 meters, N starts flashing with gear locked to 3rd. After which I need to stop and wait for 10 -15 minutes, when the reverse engages and in 10 more minutes D starts engaging very smoothly, post which the gearbox works ultra smooth.

      Hi Erica,

      If you smell gas every now and then, maybe your engine is the cause of the bucking and jerking. If your engine is not running properly, it could be causing the gas smell.

      Well I'm not sure cuz I have been taken (!!!!!!) to put it media friendly. They r hold on my van hostage for 1500.00. I paid mechanic $700.00 for a set of tires that were supposed to have been purchased at BigO to find out Swanson tires on my van. And then they told me they ordered a transmission from LKQ and when I called them to check up on it they told me no trans was ever ordered then found out they took it down the street somewhere to b repaired and now they r charging me $600 and it goes on and on.. thank you for responding if I ever get my mobile dog grooming van out I will let you know..

      Thanks for the response Eddie! I will definitely get it scoped asap...the check engine light IS on. In the meantime, there is nothing leaking below the Jeep. No wet spots or puddles where I park...so that's strange. I would also think if the trans fluid was leaking out, or into somewhere else, I would need to keep adding fluid? But its always perfect every time I check it...

      As far as the low idle oil pressure issue, I don't hear any loud hissing, but it does sound like a diesel under there! We thought it was a loose pulley, and changed out the tensioner? pulley, but it still sounds like a diesel :-/

      Hi Amy,

      Low fluid indicates a leak and the part time 4WD light is telling you there is a code being stored in the computer. I recommend having the code checked first and check for leaks. It sounds like the transmission is losing pressure internally after it warms up and all the seals are warm. The low idle and oil pressure may be a different problem like an engine vacuum leak. Do you hear any loud hissing noises under the hood at idle?

      Hi Russ,

      There is a vent on the transmission, if it's clogged it can cause the pressure to build inside the trans and blow the dipstick out of the tube. I'm not sure why it's jerking in and out of gears though. Hope this helps.

      Amy 5 months ago

      I forgot to mention, the jerk and slip in the trans are non-existent when the engine is cold, but starts again as soon as the engine/fluid is warmed up. Also, in the last week or so, the "Part-time" 4wd light keeps flashing at me randomly...not all the time, but often enough to make me worry. AND when I've been driving for a bit, the engine is nice and warm, and I stop at a stop sign, the oil pressure gauge drops to low and my check gauges light comes on...but as soon as you start to drive again, the pressure gauge returns to normal. I'm truly hoping these are all simple fixes ;-D What do YOU think? lol

      Hello Eddie,

      I stumbled across your site while trying to find answers about why the transmission in my 2003 Jeep Cherokee would be slipping...in December we had an oil change done, and it immediately started to jerk going from 1st to 2nd gear and slip going from 2nd to 3rd. After checking the fluid, we found it very bubbly and foamy, indicating it was low. We added fluid and checked it every few days, as the bubbles worked themselves out, and it DID help some, the jerk is not as pronounced from 1st to 2nd, in fact, not even there if you accelerate slowly enough, but the slip from 2nd to 3rd is definitely still there. Again, if you accelerate slowly, and let off the gas just before the shift, there is no slip. The fluid is nice and red/pink, no burnt smell or color. Do you think the trans is going out completely?

      I'd really appreciate any feedback you could give!

      Thanks! Amy
