CAMPAIGN: BRACE TO INTAKE MANIFOLD AND TRANSAXLE BOLTS
BRACE TO INTAKE MANIFOLD AND BOLTS, ENGINE TO MANUAL TRANSAXLE
Certain 1988 Pontiac Grand Am Models with Turbo-charged Engine (VIN Code M) and Manual 5-Speed Transaxle (MG1)
TO: ALL GENERAL MOTORS DEALERS
CONDITION:
--------- General Motors of Canada has determined that some 1988 Pontiac Grand Am models equipped with turbocharged engines and manual five-speed transaxles were produced with a without a brace between the engine block and the intake manifold. Without the brace, the intake manifold may crack, resulting in poor driveability and increased noise. Also, two bolts which fasten the transaxle to the engine block may be missing. Without these attaching bolts, the transaxle housing may crack, leading to loss of transmission fluid, eventual damage to internal transaxle parts, and loss of transmission operation.
To prevent this from occurring, Dealers are to inspect vehicles and if the above parts are missing, install them per the Vehicles Involved and Service Procedure sections of this bulletin.

Dear General Motors Customer:
This notice is to inform you General Motors of Canada initiating a recall campaign that includes your vehicle.
REASON FOR RECALL
It has been determined that some 1988 Pontiac Grand Am models equipped with turbocharged engines and manual five-speed transaxles were produced with a missing brace between the engine block and the intake manifold. Without the brace, the intake manifold may crack. Also, two bolts which fasten the transaxle to the engine block may be missing.
Without these attaching bolts, the transaxle housing may crack, leading to loss of transmission fluid, eventual destruction of internal transaxle parts, and loss of operation.
WHAT WE WILL DO

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.
