A revised Intermediate Band was introduced at the start of 1994 model year production. The Intermediate Band friction material was changed from a
brown material to a gray/black material. This change was made to enhance durability.
When servicing a 1994 Hydra-Matic 3T40 transaxle, do NOT assume that the Intermediate Band is burned/damaged due to its dark color. This dark
color is normal. Inspect the Intermediate Band for scoring, chunking or heavily worn friction material.
Inspect the Direct Clutch Housing and Drum Assembly for scoring or signs of excessive heat. The Intermediate Band and/or Direct Clutch Housing and
Drum Assembly should be replaced ONLY if the above listed damage is found.
This revised Intermediate Band will service all past model Hydra-Matic 3T40 transaxles and will supersede the previous Intermediate Band when service
stock is depleted.
