What Does a Transmission Pump Do?

The transmission pump supplies oil flow and pressure for the transmission clutches and lubrication. When it wears, shifts can become slow or harsh and pressure can drop.

Signs the Part Needs Replacing

Slow or harsh shifts: low pressure delays clutch engagement.
Low transmission pressure: a gauge shows pressure below specification.
Noise or overheating: a worn pump whines and the oil runs hot.

These symptoms overlap with clogged filters, low oil, air in the suction line and worn valves, so check the filters and oil level before replacing the part.

How to Order and Install the 705-21-32051 Transmission Oil Pump

Confirm your machine model, the part number and the pump model on your existing pump before ordering.
Send a photo of the old pump or the nameplate if you are not sure; LIONKITS will confirm fitment for you.
Replace the transmission oil and filter with the pump.
Inspect the suction screen and lines for debris or air leaks.
Check pressure and shift quality after installation.
