PRODUCT CAMPAIGN 86C11 MANUAL TRANSMISSION OVERDRIVE SWITCH IMPROPERLY WIRED

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.
Vehicles Involved
Involved are certain early 1986 Chevrolet Corvette models equipped with RPO MK2 manual transmission within the following vehicle parameters:

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle
Identification Number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data
furnished will enable dealers to follow-up with owners involved in this campaign.
These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle
registration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up
necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.
