Date: July, 1984
Subject: PRODUCT SAFETY CAMPAIGN 83C21 WARNER 5 SPEED TRANSMISSION FAILURE
Model and Year: 1982-1983 CHEVROLET S-10 MODEL TRUCKS EQUIPPED WITH RPO MM5 (5 SPEED MANUAL) TRANSMISSION
TO: ALL CHEVROLET DEALERS
The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within 60 days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.
To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owners are being instructed to contact the nearest Chevrolet Zone Office if their dealer does not remedy the condition within five days of the agreed service date. If the condition is not remedied within a reasonable time, the owners are instructed how to contact the National Highway Traffic Safety Administration.
DEFECT INVOLVED
General Motors has determined that a defect which relates to motor vehicle safety exists in some 1982-1983 Chevrolet S-10 two wheel drive trucks equipped with RPO MM5 (5 speed manual) transmission. General Motors has learned that the design of this transmission and the transmission fluid used, did not allow sufficient lubrication between the mainshaft and 1st gear. When in 5th gear, lack of sufficient lubrication may cause the transmission to seize and lock the rear wheels. This could cause a loss of vehicle control, and result in a vehicle crash without prior warning.
To prevent this condition from occurring, it will be necessary to replace the transmission fluid in these vehicles with a special fluid. This transmission fluid blend will provide improved lubrication between the mainshaft and 1st gear.
VEHICLES INVOLVED
Involved are certain 1982-1983 Chevrolet S-10 two wheel drive trucks equipped with RPO MM5 (5 speed manual) transmission. Vehicles involved were built within the following Vehicle Identification number breakpoint:
