General Motors of Canada Limited has determined that certain 1992 and 1993 Buick Skylark model vehicles may exhibit a condition where the Brake Transmission Shift Interlock (BTSI) solenoid becomes stuck in the engaged position and does not allow the transmission to shift out of park (on vehicles with column mounted shift lever).
To prevent this condition from occurring, dealers will replace the BTSI solenoid on involved vehicles.
Involved are the following 1992 and 1993 Buick Skylark models:
Year Model Plant From Through ---- ----- ----- ---- ------- 1992 Skylark Lansing NC656044 NC660648 1993 Skylark Lansing PC250001 PC272492

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
