Failure Symptoms

A clogged hydraulic transmission filter can initially cause subtle issues like slightly delayed gear changes or a minor increase in transmission operating temperature. If left unaddressed, these symptoms will worsen, leading to harsh shifting, potential slippage, and severe internal damage from abrasive contaminants. This can result in costly transmission repairs or replacement.

Installation Tip

Always ensure the area around the filter housing is clean before removal to prevent debris from entering the hydraulic system. Hand-tighten the new filter, then give it an additional 3/4 to 1 full turn as specified by the manufacturer.

Service Note

When replacing the transmission filter, inspect the transmission fluid level and condition, and check for any signs of metal particles that could indicate internal wear.
