TH400 Pump 1971

This TH400 pump for 1971 is remanufactured and bench-ready, 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 pump generates the line pressure the whole transmission runs on, and a tired one shows up as low pressure, slipping under load, and slow engagement when warm.

It fits the TH400 for 1971 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.
