This part cross-references / interchanges with the following part numbers:
What does this O-ring do?
It seals the joint between the transmission's oil pump and the case, keeping automatic transmission fluid contained. If a leaking pump O-ring is the cause of your ATF seepage, this replaces it.
Which vehicles does it fit?
It's a direct-fit replacement for many classic Ford, Lincoln and Mercury applications, such as the 1978-1994 Ford Bronco, 1968-1996 Ford F-250 and 1966-1979 Lincoln Continental. See the Buyer's Guide tab for the full list.
What numbers does it interchange with?
It replaces ML210, RP21, C6AZ7A248A, C6AZ7A248B, 14297, OR20 and 760004. The manufacturer part number is FO-151.
How do I know when to replace it?
Signs the pump O-ring may need replacing include automatic transmission fluid seepage or drips around the transmission oil pump. Diagnose the source of the leak before replacing.
Does the O-ring rotate with the pump?
No. It's a stationary seal — it stays seated in its groove and is compressed to form a static seal at the pump-to-case joint.
