Transmission shifting erratically (1992 Chevrolet G Series Van (G20)) rhodus in Denham Springs, LA on July 17, 2018 Transmission shifts in and out of gear and speedometer bounces around Tags: chevrolet, g series van g20 Sign in to Answer Thank Report Displaying 1 answers & 0 comments Popular Answer pushrod on July 17, 2018 Have speedometer repaired and more than likely transmission problem will also be fixed. No use going into a lot of details - this is not a recommended diy repair. https://repairpal.com/repair-shops?trk_loc=rr

It was the vehicle speed sensor (VSS). Less than $40 and easy to install.

Then you already have the answer ! Good day.
