Failure Symptoms

Initial symptoms of a failing transmission gear pump include delayed or rough gear shifts and a potential decrease in overall drive power. If left unaddressed, the pump's reduced output can lead to transmission overheating, clutch slippage, and difficulty engaging gears. Continued operation risks significant internal damage to the transmission, potentially leading to a complete loss of drivetrain function.

Installation Tip

Ensure the transmission hydraulic system is thoroughly flushed and the filter is replaced before installing the new pump to prevent contamination. Do not overtighten the mounting bolts, as this can distort the pump housing and affect its performance.

Service Note

Always replace the transmission filter and inspect the transmission fluid for debris when servicing or replacing the transmission pump.
