A/T - No 1-2 Upshift/Speedometer Inoperative
Bulletin: 85-7325-3Date: May 1985
Ref.. No.: 85-230-7325
SUBJECT: NO 1-2 UPSHIFT AND/OR SPEEDOMETER INOPERATIVE
MODELS AFFECTED: 1982-1985 RIVIERA
Final Drive Pinion Bearing:
Some Rivieras may experience a final drive noise and/or loss of drive due to an overheated final drive pinion bearing. A preliminary sign of this condition could be a loss of upshifts due to a worn governor gear in the transmission (appearing to be "apple cored," refer to illustration). Therefore, the final drive pinion bearings should also be replaced at this time.
