1992 GMC 2500 Pickup ProblemsTransmission 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.
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.
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.

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.
