PRODUCT CAMPAIGN 86C11 MANUAL TRANSMISSION OVERDRIVE SWITCH IMPROPERLY WIRED
Model and Year: 1986 CHEVROLET CORVETTE MODELS EQUIPPED WITH
RPO MK2 MANUAL TRANSMISSION
TO: ALL CHEVROLET DEALERS
General Motors has determined some early 1986 Chevrolet Corvette models equipped with RPO MK2 manual transmission may have been assembled with an improperly wired overdrive switch.
This switch will not allow the transmission to automatically be in overdrive upon restart as was intended. All other functions relating to the overdrive feature, including driver initiated overdrive activation, perform as intended.
To prevent this condition from occurring, a new overdrive switch will be installed.
