4R100 Pump 1998-1999

This 4R100 pump for 1998-1999 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 4R100 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 4R100 for 1998-1999 and ships from the USA. Confirm your year and application against your own vehicle before installing — the 4R100 ran across several updates, and matching the correct revision is what keeps the shift quality right.
