What happens if there is no 3rd gear on a 4L60E?
Without being able to lock, it won’t be able to facilitate the transfer of energy to the upper gears and the transmission will remain in 2nd gear. Your 4L60E has a set of clutches that work with both 3’rd and 4’th gear. It’s referred to as the 3-4 clutch pack. A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working.
What causes the No 3rd or 4th gear problem?
One of the most common (and most frustrating) problems that happens to the 4L60E is when it loses 3rd and 4th gear at the same time. This leaves you driving around a car or truck that screams down the road. So, what causes the no 3rd gear or 4th gear problem?
Can a bad clutch pack cause 3rd gear to stop working?
It’s referred to as the 3-4 clutch pack. A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working. In fact, once the transmission “shifts” into third, it’ll feel like you lost the whole thing. You can shift into second to get yourself home. Just be careful on the highway.
What causes a Camaro to lose 3rd gear?
Remember, we lost third gear. Notice the 2-4 band disengages, but the 3-4 clutch applies. By using this chart, we can pinpoint that the 3-4 clutches are slipping. Either they are burnt, or the apply piston has a blown seal, or whatever.

What happens when you shift to 3rd gear?
When the unit shifts to 3rd gear, pressure is applied to the release side, or 3rd accumulator side of the 2nd servo. This closes the 3rd accumulator checkball and forces the servo back releasing the 2-4 band. This same pressure also applies the 3-4 clutch. Most likely though, it’s just burned up 3-4 clutches.
Why does my 700R4 not shift out of first gear?
If the 700R4 won’t shift out of first gear, it’s most likely the governor. The governor is under the tin cover on the LH side, towards the rear of the case. You can pull the cover with large channel locks. I use a pair of dust cover pliers that remove the cover without damaging it.
Why does the transmission not go into gear when the car is running?
The transmission won’t shift and the car makes a grinding sound when the engine is running. Besides, pulling out of first gear will feel harder than normal. The transmission will shift in and out of gear without any issue when the car is not running.
What causes a car to not go into gear when in neutral?
Low level of transmission fluid. The components in modern manual transmission are always in motion even when the gears are in neutral. If there is no lubricant in the gearbox, you could have done major damage to the engine and gearbox components by running the car.
Why is my 4L60E not shifting into 4th gear?
Below are some common things that fail in the 4L60E and cause this problem. It probably goes without saying, but if you put the vehicle into second gear manually, you’ll still be able to get to where you need to go. If you end up with a bad sprag, the 4L60E won’t be able to shift into 3rd or 4th gear.
What to do when automatic transmission won’t shift into 3rd gear?
Check the Throttle Cables. Changing the fluid solves plenty of transmission issues but if the problem of automatic transmission won’t shift into 3rd gear persists, the parts you should check are the throttle cables. A defective cable with excessive slack is likely to create issues with smooth shifting of the gears.
What does it mean when your transmission Cant shift into fourth?
If it can’t shift into fourth anymore, that means that there is a mechanical issue at hand. These things wear out and eventually even a well maintained automatic transmission will fail. We’ll cover them below.
Why is my Trans bad on my 4L60E?
Trans seems noisy when moving in 1st and Reverse, noise goes away instantly if you shift to N or the transmission goes into 3rd gear: Reaction planetary is worn out due to high miles or insufficient lubrication. Not a critical failure, but not a good sign either.
When did the GM 4L60E transmission come out?
The 4L60E transmission by General Motors first came onto the scene in 1992 where it served as a replacement or upgrade to the 700R4 transmission. Although both transmissions were quite similar, it was the first time when GM shifted from a hydraulically-controlled transmission to an electronically-controlled one.
Can a bad clutch pack cause a 4L60E to stop working?
Your 4L60E has a set of clutches that work with both 3’rd and 4’th gear. It’s referred to as the 3-4 clutch pack. A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working. In fact, once the transmission “shifts” into third, it’ll feel like you lost the whole thing.
How much does a 4L60E transmission weigh?
The 4L60E Transmission has went through many changes/improvements over the years since it first came out in 1982. From bells to valve bodies, added solenoids, changes in pump and convertors. The 4L60E transmission weighs 146 pounds dry, and 162 wet.
How much fluid does a GM 4L60E need?
The 4L60E transmission weighs 146 pounds dry, and 162 wet. It requires 8.4 quarts (9.64″ torque converter) or 11.4 quarts (11.81″ torque converter) of transmission fluid, Below is a list of common transmission problems with the GM 4L60E Transmission and possible solutions to repair.

How does third gear work on a Subaru 4EAT?
Hydraulic pressure from the 2A accumulator pushes the 1-2 piston UPWARD which tightens the band. For third gear, the servo is in the 3-Release mode. In this case, hydraulic pressure from the 3R accumulator aided by the return spring pushes the 1-2 piston DOWNWARD in order to release the band.
Can a bad clutch pack Cause 3 rd and 4 th to stop working?
A bad 3-4 clutch pack can certainly cause the 3’rd and 4’th gear to stop working. In fact, once the transmission “shifts” into third, it’ll feel like you lost the whole thing. You can shift into second to get yourself home. Just be careful on the highway. The YouTube video below shows someone going through that exact situation.
Why is my transmission not shifting to third gear?
If you ignore the signs for too long, it could lead to a possible failure of the transmission. Let’s see what could be the reasons for the auto gearbox not to shift from second gear to the third. Overheating could be a reason for the gear to stick and the low fluid level is the culprit for making the transmission overheated.
Trans seems noisy when moving in 1st and Reverse, noise goes away instantly if you shift to N or the transmission goes into 3rd gear: Reaction planetary is worn out due to high miles or insufficient lubrication. Not a critical failure, but not a good sign either.
Why does my 4L60E slip in Manual 2?
Not a slight hint of a slip. Manual 2 forces line pressure to 180psi or better. This increase in line pressure allows better holding capacity to a distressed part. Also, when in ‘D’, if I take off as if I was doing a 0-60, it will shift 1-2-3 perfectly.

Check the yellow spring inside the accum housing for breakage. Also, if the accumulator housing walls are scored, the housing must be replaced. 4. 1-2 shift is delayed and harsh, may not shift into OD: TPS needs to be checked for smooth and linear electrical response over the entire range of motion. If not, this must be replaced. 5.
