# ENGINE STALL AT IDLE CLUTCH REMAINS APPLIED

REPORTS HAVE BEEN RECEIVED CONCERNING ENGINE STALLING WHEN OPERATOR FIRST STARTS VEHICLE AND THE TRANSMISSION IS SHIFTED INTO DRIVE RANGE. THE VEHICLE WILL OPERATE NORMALLY IN REVERSE. THIS CONDITION HAS BEEN FOUND TO BE CAUSED BY A CONVERTER CLUTCH SOLENOID PLASTIC SEAT DEFORMATION WHICH HOLDS THE SOLENOID IN CONSTANT CONTACT WITH THE SEAT. THE PLASTIC SEAT IS NOT RELEASED AS A SERVICE PART. HOWEVER, WE ARE OBTAINING A SUPPLY OF REVISED PLASTIC SEATS TO ENABLE US TO CORRECT THIS CONDITION WITHOUT REPLACING SOLENOID ASSEMBLIES. A SUPPLY OF THESE PLASTIC SEATS WILL BE FURNISHED TO YOUR ZONE OFFICE. SHOULD YOU ENCOUNTER THIS CONDITION PRIOR TO AVAILABILITY OF THESE PLASTIC SEATS IN YOUR ZONE, YOU CAN CORRECT THE CONDITION BY REPLACING THE PLASTIC SEAT ON THE 1982 SOLENOID WITH A PLASTIC SEAT REMOVED FROM A 1981 - 250C OR 350C TRANSMISSION SOLENOID SUCH AS SERVICE PART NUMBER 1997511 OR 1997526. TO REMOVE PLASTIC SEAT, PUSH ONE OF THE RETAINING TABS TOWARD CENTER OF SOLENOID AND LIFT SEAT FROM SOLENOID. TO PREVENT LOSS OF THE BRASS VALVE AFTER YOU HAVE REMOVED THE PLASTIC SEAT, IMMEDIATELY TAPE THE BRASS VALVE IN PLACE TO PREVENT IT BEING LOST UNTIL THE NEW PLASTIC SEAT IS INSTALLED. WHEN INSTALLING PLASTIC SEAT ON THE SOLENOID REMOVED FROM THE VEHICLE, BE SURE BRASS VALVE IS IN SOLENOID AND HOLE IN PLASTIC SEAT IS DIRECTLY OVER VALVE. IF PLASTIC SEAT DOES NOT HAVE AN O-RING TO SEAL AGAINST VALVE BODY, THE SERVICE GASKET PART NUMBER 25500317 MUST BE USED WHEN ASSEMBLING SOLENOID TO TRANSMISSION. NOTE: ANY PLASTIC SEAT WITH O-RING IN SEAT DOES NOT REQUIRE A GASKET BETWEEN SEAT AND VALVE BODY. YOUR ZONE OFFICE WILL PROVIDE YOU WITH A SOLENOID PLASTIC SEAT TO RESTORE ANY PART STOCK SOLENOID USED TO RESOLVE CUSTOMER COMPLAINTS.

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.
