I put the servo in because when I would really get on it it would not always hold 2nd gear. Anyhow, did rear main seal, installed trans back in and drove around maybe 100 miles.

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.

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.

Your shift solenoid A (also known as shift solenoid 1 - 2), may not be releasing. First gear requires A solenoid and B solenoid to operate, 2nd gear requires A solenoid to release. A quick test would be to manually shift to 4th gear . If it shifts into 4th , which is A operated and B released, that would be a pre [y good indication. The 1-2 shift failure on the 4L60E is often due to a faulty throttle position sensor (TPS). Test the sensor (there should be a smooth, linear electrical response over the range of motion) or substitute a known good unit. A more serious cause of 1-2 shift failure on the 4L60E is a leak in the 2nd gear apply circuit (servo assembly or 1-2. 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.

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. 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. Never reduce the 1-2 accumulator piston stroke. Never leave out the 1-2 checkball. Never over-drill the 1-2 feed hole.

4l60e no 3rd or 4th gear . Working on a truck for a guy he has ls with a 4l60e the harness and PCM is for a 4l80e. The PCM has been reprogrammed by street and performance. The tranny plug has been repinned and the correct pins and wires added. The problem is that the tranny will not shift under throttle if you let up it shifts fine. Ideally, you’ll want a final drive gear ratio of about 10:1 in first gear. The 4L80E’s 2.48, when multiplied to the rear axle ratio of 4.10:1, yields a close 10.16:1 – whereas the 4L60E’s gear ratios are harder to work with, even with another rear axle ratio like 3.73:1. Changing the gear ratio can improve the car’s performance, yield.

The overdrive gear is gear number four. As the 4L60E ages, one of the most common problems that it develops is that it won't shift into overdrive anymore. Without overdrive, your vehicle turns into a time machine and takes you back to an era where it was the norm for a vehicle to scream down the highway at 3000 RPM.

A 6l80/90 is a proper upgrade. can handle alot of abuse, 4:1 first gear (better than stock 3:1) and two overdrive ratios, at least fifth gear would be a better over drive gear for a truck with 35s than the 4l60e's 4th gear.

Servo Pin Bore While it’s called a 2-4 band, the servo and band operation are critical for 2nd, 3rd, and 4th gears. Here’s why: The band is applied in 2nd and 4th gears. But on the 2-3 upshift, direct apply oil is sent to the back of the 2-4 servo. For that shift, the 2-4 servo acts as a 3rd gear accumulator, because it still. 4L60E NO 2nd.
