Transmission Pump

By Andy Y, January 20, 2009

The transmission pump is a hydraulic pump that circulates transmission fluid trough the transmission and its cooling system. It also builds the hydraulic pressure necessary for the transmission to operate.

Symptoms of a Bad or Failing Transmission Pump

  • Abnormal whine type noise
  • Transmission fluid leak

Transmission Pump Related Repair Advice

  • If the front pump seal is being replaced, the sealing surface on the torque convertor should be inspected for damage. A damaged sealing surface could damage the newly installed pump seal.
