DATE OF PRODUCTION CHANGE: (Figure 2)
The new Direct Clutch drum went into production July 11, 1989, (Julian Date 192) for all Willow Run built transaxles and July 12, 1989, (Julian Date

SERVICE PROCEDURE:
This new Direct Clutch Drum can be used on previous model HYDRA-MATIC 3T40 transaxles built since (model year) Start of Production - 1985.
Do not attempt to use the new Direct Drum in transaxles built previous to model year 1985 because the return spring and snap ring groove location will
not allow 1980 to 1985 model internal components to assemble into the new direct clutch drum.
If an intermediate band failure occurs, inspect the outer wall of the direct clutch drum using a flat edge ruler (Figure 1). If there are dips in the drum
between the ruler, the drum should be replaced.
