1992 Chevrolet G Series Van (G20) Problems

Flush brake fluid every 60,000 miles

Our technicians recommend flushing the brake fluid every 60,000 miles.  Brake fluid that is dirty may cause problems in the brake system.

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.

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...
