Speedmaster Polished Finned Aluminum TH400 Transmission Oil Pan Kit W/ Bolts & Gasket

Looking to dress up your TH400 while keeping it cool?

This Speedmaster finned aluminum pan is exactly what you need.

It's brand new, polished to a mirror shine, and comes as a complete kit with mounting bolts and a gasket included.

The part number is PCE221.1005, and it's designed specifically for the Turbo 400/221 automatic transmission.

Those fins aren't just for looks—they help dissipate heat to keep your trans fluid cooler.
