[00-UP] Automatic Transmission Gasket Allison 1000 Pump Body O-ring

External leaks and lost line pressure both trace back to gaskets and seals that hardened with age and heat.

1000 pump body o-ring. This is the sealing set a rebuild replaces from end to end.

O-ring groove dimensions are what decide whether a seal holds pressure or takes a set. Shipping weight is 1 lb.
