Transmission Adapter – Mopar (5018174aa)

Transmission Adapter is a service part for the engine, transmission or driveline. Because several build codes can share the same external description, the part number is the only dependable match.

Replace the Adapter when inspection shows wear, cracking or leakage that the surrounding components cannot explain. Rule out the cheaper causes first.

This Adapter is listed as part 5018174aa (Transmission Assemblies). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

The stock here is genuine MOPAR, and this Adapter keeps the original engineering number, which matters once a number has been superseded more than once.
