|No reverse or over drive||Chris patterson||2-14-08|
|Went out to the garage today to take my 1991 gmc 3500 4x4 up to the car wash and no reverse??? checked the fluid it was fine. Decided I would take it up for the wash drive was still working. On the way there I notice no overdrive?? I have the 4L80 E trans Does this sound like a mechanical problem or electrical? THANKS|

|Check the fluid level. Fluid pressure may not be enough. The reverse have a much higher line pressure than the forward gear ranges. Reverse Servo seal failure. A simple fix but since the transmission is out of the vehicle. They should do a check for other wear.|

|I was browsing thru the problems with the 4l80e and found a great site for the overdrive problem.|
I just replaced all the solenoids and have great shifts but no overdrive.
