NEW REVERSE BAND APPLY PIN GAGE
MODELS/YEARS 1989 CUTLASS CIERA, CUTLASS SUPREME, EIGHTY- EIGHT, NINETY-EIGHT AND TORONADO EQUIPPED WITH THE 440-T4 TRANSAXLE (RPO-ME9)
ASSEMBLY COMPONENT CHANGE:
A new reverse band apply pin gage is required for all 1989 and 1990 THM 440-T4/HYDRA-MATIC 4T60 models. The 1989 and 1990 transaxle calibrations require a longer reverse band apply selection sets. This new gage pin will make the band apply pin selection about 0.080" (2mm) longer or two sizes longer than if gage pin J 33382-2 is used.
SERVICE PROCEDURE: (Figures 1 and 2) ------------------ When servicing a 1989 or 1990 model year transaxle, use the proper year band apply pin selection chart and gage pin J 33382-10. Gage pin J 33382-10 has a hex head for easy identification.
IMPORTANT: Do not use the new gage pin J 33382-10 for selecting the proper 1-2 band apply pin. Calibrations will be affected. Reference Figures 1 and 2 for proper 1 -2 band apply pin gage.
SERVICE MANUAL REFERENCE:
This product change information is shown in the THM 440-T4/HYDRA-MATIC 4T60 Automatic Transaxle Unit Repair section of your 1990 Service Manual.
SERVICE TOOL INFORMATION:
The reverse band apply pin gage J 33382-10 is an essential tool. Shipping will take place later in the 1989 calendar year from Kent-Moore.
