General Motors has determined that CERTAIN 1993 M/L and G Vans may experience a condition, at temperatures below 32 degrees Fahrenheit, where the transmission will not shift out of PARK with the brake pedal depressed. To prevent this condition from occurring, dealers will replace the cruise control vacuum release valve and check and adjust the BTSI solenoid cable as needed.
NOTE:
The Brake Transmission Shift Interlock (BTSI) System is designed to prevent the automatic transmission from being shifted out of PARK unless the brake pedal is depressed.

The specific vehicles involved in this campaign have been identified by Vehicle Identification Number (VIN) Computer Listings.
