Failure Symptoms

A failing transmission gear pump may first present as delayed or rough gear engagement and a noticeable whine from the transmission housing. If ignored, the pump's output will decrease, potentially leading to slipping gears and loss of drive power. Continued operation risks severe internal transmission damage due to inadequate lubrication and hydraulic pressure.

Installation Tip

Thoroughly clean the transmission case and magnetic drain plugs before installing the new pump to remove any metallic debris. Ensure the pump's drive shaft engages correctly with the transmission's drive mechanism to prevent damage.

Service Note

Replace the transmission oil filter and inspect the transmission oil for any signs of metal shavings or debris.
