1992 Chevrolet G Series Van (G20) 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.

Idling Problems Due to Vacuum Leak in Throttle Body Gasket

An engine vacuum leak may develop from the throttle body gasket causing a higher than normal idle speed. Failed gaskets should be replaced.

Alternator May Fail and Cause Noise and Dead Battery

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

I just picked up my van last Aug. (2013) and love it. The only issues I am having is that when hot outside it vapor locks (I was told). It turns over but then dies, will restart but then dies. If I can get it rolling then it runs great and when not hot weather it runs great. There is a switch for turning off lights while doors are open but doesn't seem to work, so interior lights stay on when d...
I was driving my 1978 GMC 3/4 ton van from Connecticut to Maryland for the Thanksgiving weekend, 1985. 10PM at night,65MPH, extremely light traffic. In those days, the CT. turnpike had a toll plate about every 20 miles or so, 35 cents just to break up the monotony. There was a light rain falling so I was using "intermittents" to sweep the glass. Temp was right at freezing but I wasn't scared, I...
