Models
Affected:
1986-92 6000, SUNBIRD, GRAND AM, FIERO, LEMANS, GRAND PRIX AND TRANS SPORT MODELS WITH 3T40
TRANSAXLE APPLICATIONS:
1986-92 HYDRA-MATIC 3T40 TRANSAXLE (RPO MD9)
TRANSAXLE MODELS:
All
CONDITION:
Some 6000, Sunbird, Grand Am, Fiero, LeMans Grand Prix and Trans Sport models equipped with HYDRA-MATIC 3T40 transaxles and manufactured
the model years 1986 through 1992 may exhibit symptoms associated with wear in the low/reverse clutch pack. These symptoms are:
*
Transaxle slips in manual low or reverse gears
*
Transaxle inoperative in reverse gear
CAUSE:
(See Figure 1)
If this condition exists (and upon inspection of the low /reverse components), and it is noted that the piston outer lip seal is cut due to piston overtravel,
this overtravel could possibly cause flattening of the low/reverse release spring (655) and deflection of the low/ reverse clutch spring retainer (656).
CORRECTION:
