AT540 [70-UP] Automatic Transmission Gasket Allison Pump to Case

Rubber that has cycled through enough heat stops returning to its shape, and a seal that does not return does not seal.

AT540 pump to case gasket. Each seal is formed to the groove and bore it serves.

The sealing surfaces have to be clean and flat for any gasket to do its job. Shipping weight is 0.8 lb.
