CAMPAIGN: UPPER TRANSMISSION OIL COOLER LINE SEPARATION
SUBJECT: UPPER TRANSMISSION OIL COOLER LINE SEPARATION
"CANADA ONLY"
Models: 1992-95 Chevrolet Lumina/Minivans and 1992-94 Pontiac Trans Sport with 3.8L Engine
TO: ALL GENERAL MOTORS DEALERS
General Motors of Canada Limited has determined that a defect which relates to motor vehicle safety exists in certain 1992-95 Chevrolet Lumina/Minivans and 1992-94 Pontiac Trans Sport model vehicles.

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.
