4l60e 3 4 shift problem

Burnt 3-4 clutch packs are notoriously common in the GM 4L60/E family of transmissions. Tech hotlines and internet bulletin boards are often jammed-up with people pleading for help with this 3-4 roasting. Some technicians get frustrated and throw multiple Hail Mary replacement parts at the transmission when facing this issue We'll look in detail at a few more slippage-specific situations of 4L60E transmission problems. 4L60E No Third Gear. The 3-4 clutches can wear out quickly. If you find a lot of problems when you are shifting from 3rd to 4th, this could be the issue. Like most of these cases, the transmission will need a full rebuild 4L60E Question - suddenly lost 3/4 Gears. It worked great for four days, had all gears, shifted at proper RPM/Speed, and all seemed great. Then, suddenly, I lost third and fourth gear. There was no slipping or other indication of a problem, and it still doesn't feel like a slip, it feels like it shifts into neutral instead The problem? 3-4 clutch pack failure! Take the bell off, pull the pan, take out the filter and solenoids, pull the pump and drone, separate the drone, and what you will see is a burned up 3/4 clutch pack. But what causes it? The 3/4 piston rubber seals shrink from heat and age. Hydraulic pressure blows around it and the clutch pack fries Most of the problems that occur with a 4L60E shift solenoid are caused by the coil wire going bad in some way. It can go bad in a couple of ways. The plunger can also get stuck. We'll cover the why and the how here. You can test the solenoids with an OHM meter. You should be looking for 20-30 ohms of resistance

4L60E No 2nd Gear, Shifts 1-3-4 (continued) When the transmission is commanded into second gear the ECM turns off shift solenoid A, this allows the 1-2 signal oil to exhaust. The 1-2 shift valve is stroked to the 2nd gear position by the 1-2 shift valve spring. There are two possible solenoid related issues that could cause a no 2nd gear. Trans ID for the 4L60E is located on the passenger side of the case about halfway up the trans. It is 0.5 inch tall cast in lettering. Can't miss it. I just rebuilt my 4L60E because it was slipping in 3rd gear. Found out the 3rd gear clutch pack was fried as well as the stator shaft ID if the 3/4 clutch air gap is set correct and the 3/4 piston is good when it was air checked and the input drum is good and not cracked.and the 2/4 servo apply seals are good and not cut. there is a problem with the valve body assembly and or the spacer plate under the valve body.hopefully if it is the valve body problem that it did not damage the 3/4 clutches as it has been slipping and or flarin The 1-2 shift is harsh and delayed. Not only do 4L60E transmission owners experience a delay or harshness in 1-2 shift, but there have also been reports of an inability to shift into overdrive.

The 4L60E transmission platform has been in service from 1993-2015, that's 22 years. It amazes me when a transmission that has been around for this long can throw a new twist on a common problem and blindside you. Let us have a look at the systems and potential problems in a 4L60E that can cause a harsh 1-2 shift A problem with one or more of the solenoids can cause a lack of pressure, resulting in hard, soft or delayed shifts. A failed shift solenoid can also cause transmission slippage, where your engine revs faster but the car stays at the same speed. Transmission won't shift gears: A faulty shift solenoid can prevent fluid pressure from activating.

3 Symptoms Of A Failing 4L60E Transmissio

  1. g of this shift can cause a momentary torque reversal of the output shaft that results in a clunk noise. This same torque reversal can also occur on a 3-2 downshift when the 3-4 clutch is released and the 2-4 band applied
  2. 3. 1-2 Shift shudder at WOT; delayed or abnormal 1-2 shift; There's a problem ONLY on the 1-2 shift: 1-2 accumulator piston cracked or stuck cocked in the bore. Check the yellow spring inside the accum housing for breakage. Also, if the accumulator housing walls are scored, the housing must be replaced. Easy fix in the pan
  3. (2-3 & 3-4 feel 'normal', which in GM-parlance is a bit on the soft side - I had a '98 Grand Prix with a 700R4 (IIRC) - you could barely feel the thing shift, under light- to normal throttle) I have tried lifting throttle to tame the shift, but have noticed that I seem to have flare - put my foot back on the throttle and it's as if it were in.
  4. D0702 Base Pressure 2>3 Shift D0703 Base Pressure 3>4 Shift I'm in the middle of building a 4L60E using the Sonnax HP-4L60E-01 Performance Shift Pack and I'm worried that not having this tuned correctly will allow the clutch packs to slip with boosted power etc. Thank you
  5. d this transmission is based on the 700R4 which was put behind much weaker powerplants. It needs to be beefed up to last
  6. When your 4l60e starts to act up and not shift correctly, one very likely culprit is the shift solenoids. There are 2 shift solenoids in a 4l60e (1-2 and 2-3), and both control up and downshifts with fluid passing through them when commanded to do so by the computer. However, when they go bad, you will notice very quickly

Another weakness of this transmission is the clutch package 3-4. Also, many complaints include the destruction of a planetary row of one of the transmissions. It is usually the result of overload and its overheating. By the way, the temperature of the unit (4L60E) is important, not less than that of the engine, so it is necessary to keep clean. Re: 4l60e no 2-3 upshift on wot or almost wot. Sign In. Its very possible you may have a sticky shift solenoid, does this problem happen more when the car is cold, or when hot, or at any time hot or cold. To make a 2-3 shift, the band gets released and the top clutch of the input drum comes on, that top clutch is called the 3-4 clutch, this is. Re: 30 common problems with the 4L60E. Mar 30 2015, 3:30am. I can add some information if needed but transmission operation is controlled by TPS, MAP/MAF, speed sensor and a couple others but those are the big 3.

This valve controls TC lube and temp, I believe. The tranny guy informed that my new TC was probaly in bad shape and would need rebuilt. I read many threads about shift kits and rebuilding 4l60e's and I never read anything about this tcc valve problem The 3-4 clutch pack is a common failure item in this transmission, due mostly to the design of the input drum where the 3-4 clutch resides. The clutch pack installs at the rvery rear of the drum and is held in place by a snap ring. The thin backing plate of the clutch holds back the apply pressure with only the snap ring to keep it in place Some customers may comment about a 1-2 shift flare with an end bump or a harsh 1-2 shift at light throttle. Cause This condition may be caused by the 2-4 band apply time extending through the 1-2 accumulator stroke. Correction 1. Verify the customer's concern. 2. Remove the valve body.
