Cutlass V8-350 5.7L DSL (1984)
All THM 200-4R models built after July 7, 1989 (Julian Date 188), were built using the revised spacer plate.
SERVICE PARTS INFORMATION:
All past model spacer plates for service will include the new identification tab when current stock is used up.
The Lo/Reverse feed hole revision only affects THM 200-4R transmission models that were initially built with the Accumulated Neutral to Reverse
Garage Shift Package (reference Dealer Technical Bulletin 88-T- 145). Part numbers for reversed 1988-89 spacer plates are listed below.
Part numbers and identification letters have not changed. Therefore, when servicing a THM 200-4R spacer plate, order the usual part number and the
replacement part will be the updated spacer plate.
