The 10 Most Common Problems With the 4L60E Transmission
While the 4L60E transmission is considered one of the best by GM, it is not without its flaws. Unfortunately, transmission issues have been said to occur even with the best care and maintenance.
Below are a few of the most common problems that are known to plague the 4L60E transmission, including why your vehicle cannot shift gears and how to know if your pump is bad.
We also offer possible causes, fixes, and costs for your convenience. Please keep in mind that these aren’t definitive solutions for every case.
1. 4L60E Transmission Third Gear Problem
The most common gear issue for a 4L60E transmission is a loss of third gear. This problem typically occurs out of the blue. You can put the vehicle into drive and shift it into second gear without issue, and just as you try to go into third, nothing happens. It’s as if your vehicle is stuck in neutral and can’t proceed. This problem happens because the piston rubber seals have shrunk from age and heat.
The Fix
To fix this issue, usually, you’ll need a new piston and clutch. A new piston’s average cost is between $1,000 to $5,000, and the average price of a new clutch can cost between $900 to $1,800. Although, pricing will depend upon your vehicle and the shop you use.
2. 4L60E Transmission Second Gear & Reverse Problems
The second most common gear issue for a 4L60E transmission is the inability to shift into second gear or go into reverse. This problem typically appears when the drive shell breaks.
The Fix
To fix this issue, you’ll need to replace the drive shell. Unfortunately, replacing the drive shell means you’ll need to remove the transmission and rebuild it. A new drive shell can cost you between $50 and $100.
3. 4L60E Transmission Difficult Second Gear Problem
The third most common gear issue for a 4L60E transmission is difficulty shifting into the second gear. A 4L60E transmission experiencing this issue will feel like it has a shift kit installed. That means it will feel like you need to apply more force when shifting into second gear. This problem typically occurs when your TCC regulator valve wears out.
The Fix
You’ll need to replace the TCC valve regulator to fix this issue. To replace the TCC valve regulator, you’ll need to pull the fan and filter. Then remove the selenoids, wiring harness, and valve body bolt. Next, lift the valve body and turn it over. The TCC valve regulator is under the valve body. A new TCC valve regulator can cost you around $65.
4. 4L60E Transmission Loss of Third or Fourth Gear Problem
A complete loss of third or fourth gear can occur. If you cannot shift into third or fourth gear, a worn-out clutch is typically the cause of a complete loss of third or fourth gear.
The Fix
To fix this issue, you need to replace the clutch. A professional mechanic or specialist should perform this repair. The average price of a new clutch can cost between $900 to $1,800. Although, pricing will depend upon your vehicle and the shop you use.
5. 4L60E Transmission Loss of All Gears / Bad Pump
A loss of all gears can occur. This problem typically occurs if your vehicle experiences a total loss of fluid or if pump failure occurs.
The Fix
You should first check your vehicle’s fluid levels to fix this issue. Be sure to turn your engine off before doing this. If the fluid levels appear correct, start the engine and double-check the levels. You will know the pump is broken if the fluid levels don’t decrease while the engine is running. If the pump is broken, it will need to be replaced. The average price of a new pump can cost between $400 to $1,200. Although, actual pricing will depend upon your vehicle and the shop you use.
6. 4L60E Transmission Slipping Problems
A common issue for all types of transmissions, slipping occurs when problems with the transmission fluid happen. For example, transmission fluid issues may arise when the fluid level is low. In addition, a leak or burned or old part can cause the problem to become persistent. Common indicators of slipping may include burning odors and terrible metal noises like whining or grinding. Furthermore, the check engine light might even pop on.
The Fix
To fix this issue, you should check your fluid level by removing the dipstick and determining if the levels are low. If the levels are low, you can try refilling the fluid and seeing if that resolves the problem. If the levels aren’t low, the problem could be any number of causes, and a professional mechanic or specialist will need to determine the exact cause. Pricing will depend on the part that needs replacing, the vehicle, and the shop you use.
7. 4L60E Transmission Noise Problems
A noisy transmission might occur when shifting into first gear or reverse, and a few different things can cause it. The usual cause for this problem is a lack of lubrication. Typically, shifting into neutral or third gear will cause the issue to go away. Still, it is only a momentary reprieve, and the noise will return when shifting back into first gear or reverse.

You’ll need to replace the cooler line if the blockage doesn’t come completely undone on the first try. The average price of a new cooler line can cost between $100 to $500. Although, actual pricing will depend upon your vehicle and the shop you use.
9. 4L60E Transmission No Overdrive Problem
Over time you may notice that your 4L60E transmission does not want to shift into overdrive. The overdrive is essentially the fourth gear, which can arise due to several issues—causes for this issue range from linkage issues to band failure. To determine if the issue is simply a linkage issue, you can try shifting in OD down to D, 2, and then 1. You most likely have a linkage issue if you didn’t hear or feel the typical three clicks as the gears shifted. A
The Fix
The transmission will need to be removed and rebuilt to fix this issue. Since there a multiple causes for this issue, a professional mechanic or specialist will need to determine the exact cause. Pricing will depend on the part that needs replacing, the vehicle, and the shop you use.
10. 4L60E Transmission Shift Solenoid Problems
If your 4L60E transmission is experiencing any of the following issues, the most likely cause could be its solenoid. A faulty solenoid can cause problems such as erratic shifting, failure to downshift, or being stuck in neutral. Furthermore, a broken solenoid wire will cause severe vibrations or higher than average voltage. However, a melted solenoid wire will cause a drastic transmission temperature or higher than average voltage.

I rebuilt won’t hold 4th gear shifts back and forth to 3rd any suggestions
I just rebuilt my factory trans ran good reverse started going out so I took it to the shop about a month ago and yesterday it locked up on me it was running fine it just quit and the oil smells like electrical burn
How does 2nd feel? I’d check the servo
What was your outcome of this . I seem to be having the same issue
I have been having the same issue for months. My transmission needed to get rebuilt anyways so I did that and the problem is still there. I’m pretty lost on what to try next but im thinking maybe it’s getting too hot and the fluid is losing viscosity so it won’t hold OD?
Same here – been having the problem with erratic shifting back and forth between 3rd and overdrive, for two years. Sometimes I can drive 200 miles with no problem, and other times it’s a pain in the ass. I haven’t been able to find any information on it, except some references that state the Body Control Module (BCM) could be the problem (?). I tried swapping out three BCMs from either a 1998 or a V6 (mine is a 1999 2.2 L). They were the closest I could find at a salvage yard, but with all of them the engine would start and then immediately die, then not start, again. Other web sites indicate a faulty Transmission Control Module, but I can find no further information on that.
BTW, The only error code I ever get is that the transmission filter needs changed, but changing it and replacing with new fluid made no difference.
Adjust shift cable. Actually could be that simple. Good luck 👍 thanks Greg
03 Avalanche 1500 w/173000 miles has run perfectly for several years and suddenly this morning it won’t stay in 1st or 2nd gear. Fluid checked and it was low. But still has issues. I’ve never heard of the tranny just suddenly doing this. It has never slipped or done anything like this prior. Ideas?
Same here. Mine keeps shifting back and forth between 1st and 2nd at around 10-15mph.
89 gmc 4×4 1500 with a 360 motor which is new and transmission is also new. My problem is the truck does not accelerate when I give it gas, what might be the problem?
There are several potential reasons why your truck might not be accelerating when you give it gas. Some common possibilities include fuel delivery issues, air intake problems, ignition problems, transmission issues, and ECM problems. To determine the exact cause, it’s best to have a mechanic diagnose the issue.
My 95 4×4 4l60e drives fine for a while then at some point won’t shift into 3rd gear. I limped it home in second and after 10 min. decided to try it agian. All worked as it should for about 4 days today it did the same thing just wouldn’t shift past 2nd. I tried it manually and still nothing. Help me out what’s going on here. Side note this is the 2nd transmission to do the same thing on me.
There are a few potential causes for this issue. It could be a problem with the transmission fluid, such as low fluid levels or dirty fluid. It could also be a problem with the transmission solenoids or sensors. Additionally, it could be an issue with the valve body or the torque converter.
It’s best to take your vehicle to a qualified mechanic who can run a diagnostic scan to identify any error codes and perform a transmission fluid check. They may also need to conduct a more thorough inspection of the transmission system to identify the root cause of the issue.
If this is the second transmission that has had this issue, it’s possible that the problem is related to a larger issue with the vehicle, such as an electrical problem or an issue with the engine. A mechanic can help you determine if this is the case and what steps you should take to resolve the issue.
I had do that and it was the ignition switch
Transmission in my 95 k1500 pickup won’t shift past first, would any of these fixes help?
94 k1500 just bought a rebiult transmission from a reputable dealer of rebuilt transmissions. Put it in drive it wants to move but doesnt. I have to put it in first get up to 10mph then shift to drive and it shifts fine for the remaining gears. What could cause this?
I have the same problem with my 94 k1500 on a new rebuild. Still haven’t found the problem yet.
I have one that will not go into gear until you stop and do the reset procedure then it goes into gear goes fine doesn’t slip until I stop then lose all gears until I do the reset again goes again so I stop lose all gears again till I reset again what could be the problem
Hey I’ve got a 97 gmc jimmy with 4l60 shifts fine at 1/2 throttle or so at any speed but if I get on it.it doesn’t want to downshift to 2nd and if I manually shift it.it acts as if it’s slipping any thoughts
Cycling from D to 3rd rapidly could be the converter lockup solenoid. Requires machining the valve body for a steel insert. After steel insert/rebuild I’ve had no further issues for 72k miles. It’s pricey, but the aluminum valve body seat can’t handle the steel solenoid actuator long term.
03 S10 4-door
Hii so I’m guessing but please confirm I had my 4L60E box rebuild with shifter upgrades and so forth the old box randomly started hitting neutral when in D or 3rd and sometimes while on passing speed I could manually shift to 3rd it might or might not take but can’t floor it otherwise jumps out and sometimes makes a big bang in box now the same happened to new rebuild box with in same day of return so we redid software and months after old box packed up rebuild done that night before it happened to new box my mechanic did some changes to remapped software could this be a weak old fashioned TCM and Pcm and just need to set their ratios and limits within 2004 V8 LS 5.7 rate and then only boost up once TCM and Pcm been replaced with better high performance tipes
1995 Corvette – I’m on my third 4L60-E. Original lasted ~80,000 miles. Bad slipping in 3 and 4th gears, had it rebuilt for $1,900. That one crapped last week (8/2023) at 150,000 miles, had it rebuilt for $3,400. Knowing this trans is not the best, I DO NOT beat on it. And for that matter I never beat the crap out of my cars.
Hopefully this is the last rebuild. All other parts and service costs haven’t equaled the $5,300 (plus tax) that the 4L60-E has cost me. (I do my own maintenance and repairs, except transmissions).
I’ve got a 2011 Suburban LTZ with 50k miles, having trouble shifting into 2nd and I lose power when going up a hill while in 2nd…but once I push down on the pedal, I get lots of power to speed up the hill, if I take my foot off the pedal, the power fades again.
I have a 2003 z71. With about 180k miles. Hit a dip at, got to the next intersection. Transmission refuses to respond. Press the pedal. The engine just revs. Solinoid? Bad pump? Any help. Appreciated.
This might seem crazy but both my 2002 Yukon XL and my 2004 Buick Rainier had shifting problems between 1 and 2nd and in both instances it was loose clamps on the air intake hoses. The change I’m temperature I believe caused it between seasons. It was sucking air so it wouldn’t shift right. This seems to be a common problem because I continually have to tighten the clamps.
I have a 99 C5 Corvette with 4L 60 E transmission doing 90 miles an hour I accelerated RPMs went to about seven or eight I believe and acted like I had a restrictor plate like most cars do at 120 wouldn’t allow it to go no faster. Hi Temp transmission Came on the cluster no codes just high temp pull off the freeway put it in park and went through. All gears proceeded to drive transmission would not go into third gear change fluids and filter. Still no codes no high temp no more is there something that I can do to get third gear back without replacing transmission?
