TH400 Master Rebuild Kit

This TH400 master rebuild kit is new, so when the unit in your transmission is worn out you install a known-good part instead of chasing the failure piece by piece. In the TH400 the master rebuild kit restores every friction, steel, seal, and gasket in the unit, and a tired one shows up as a high-mileage rebuild where you want everything new at once.

It fits the TH400 and ships from the USA. Confirm your year and application against your own vehicle before installing — the TH400 ran across several updates, and matching the correct revision is what keeps the shift quality right.
