Here is an update. I checked line pressure in in park and drive line pressure is between 55 and 200 psi. 55 at iddle and 200 psi at WOT. Trans shifts and feels fine in all forward gears. Line pressure in reverse was 65 to 70 psi at idle. When I started to accelerate ( lightly) in reverse line pressue went up to 120psi.BTW, 'limp mode' is a failsafe for electronic issues -- 3rd is the only gear in the 4L60E that doesn't require electronic activation, so it became the 'limp home' gear. The 3rd clutch breaking is a physical problem, so when it goes, the trans will flare above about 25-28 mph, as it can't shift to 3rd at that point, automatically or manually.

4L60-E PWM Application Sample. As a further effort to improve fuel economy and prolong the life of transmission and engine components, PWM control evolved into EC3. The valves and solenoids remain (virtually) the same as with PWM operation, but the control strategy and TCC lining have again undergone changes.

Put the shifter in drive and see if it will move forward. If it does, problem is likely in the harness or solenoids. If not, the problem is in the case (pump, 3-4 cluch pack, input sprag, etc). No movement in any gear is either pump, input shaft splines stripped or t case if a 4wd.Early 4L60 transmissions ('82-'86) use a reverse input drum that has a rectangular hole where the fluid enters the drum. In 1987, when the auxiliary valve body was first introduced, the reverse input drum feed hole was changed to a smaller round hole (.095") which became the orifice to feed the drum. If an early square hole drum is used …B52Bombardier1. Put a pressure gauge on it to check the internal line pressure. Reverse typically calls for the highest operating pressure of any 4L60E gear at idle and I will predict that yours will be low. At that mileage, your pump in the front of the transmission is probably worn out. That transmission owes you nothing.#1 · Dec 7, 2015. I have a 99 Yukon 4x4.

The easiest way to diagnose a bad or failing torque converter clutch is when there is no lock up. The 4l60e torque converter is designed to lock up primarily in 4th gear (can also be enabled to lock up in 3rd gear as well), so when it doesn’t lock, it’s quite noticeable.4L60E torque convertor shudder. I have a 1993 Suburban, 1/2 ton 4WD with the 4L60E transmission. In 4th gear, overdrive, under load the transmission will shudder.

Put moderate pressure on the "nipple" on the servo cover. If the cover will recess into the transmission 1/4" or more this will prove the band is worn out and most likely the reason there is no 4th gear. The 4th piston does not have as much travel as the 2nd gear piston.Sonnax Forward and Reverse abuse bore plug 77754-21 resolves these problems.
