1992 GMC 2500 Pickup Problems

Transmission Fluid Leak, Erratic Shifting

On the 4L80-E Transmission (Diesel and 7.4L gas engine), Transmission fluid may leak through the electrical connector on the side of the transmission, damaging the wire harness and causing the transmission to shift erratically. Our technicians tell us there are updated shift solenoids, an internal  transmission harness, and a connector pigtail available to correct this fault.

Quick-connect fittings for heater hoses may leak engine coolant

The quick-connect fittings for the heater hoses tend to leak engine coolant. This problem commonly occurs because the metal housing has become brittle, which can break and cause leaks.

Alternator May Fail and Cause Noise and Dead Battery

The alternator may fail causing the battery to go dead, or an abnormal noise may develop. The dash warning light may or may not illuminate. A failed alternator will require replacement.

Seat Bolts Loosen And Fracture

The bolts that secure the seat recliner to the seat frame may loosen, fatigue and fracture, causing the seat back to recline suddenly. Dealers will remove all foam and fabric sandwiched between the recliner and frame, install washers between them, and install new bolts, tightening them to a higher torque specification free of charge to resolve the concern.
