Transmission filter kit for compatible 01M four-speed automatic transmissions. Maintains clean hydraulic fluid and correct pressure for reliable shifting performance.
$14.99
The 01M 398 009 transmission filter kit provides the essential service components needed to maintain clean hydraulic fluid in compatible 01M four-speed automatic transmissions. The filter screens contaminants from the fluid before the hydraulic pump circulates it through the valve body and clutch packs, protecting precision internal components from abrasive wear.
Over time, the filter accumulates metallic particles, clutch material, and fluid breakdown byproducts. A restricted filter reduces hydraulic pressure throughout the transmission, directly affecting shift quality and internal lubrication.
The 01M 398 009 transmission filter kit supports consistent hydraulic pressure across all shift events. The 01M transmission relies on precise pressure delivery to engage clutch packs and control shift timing. A clogged filter starves the hydraulic circuit, causing delayed engagement, harsh shifts, or slipping under load.
Replacing the filter at the correct service interval removes accumulated debris before it restricts flow. Pairing this service with a fresh pan gasket and the correct OEM-specified ATF fluid restores the transmission’s hydraulic baseline and extends the service life of internal components.
Monitor the transmission for these indicators that the filter has reached the end of its service life:
Delayed or sluggish gear engagement from a stop.
Harsh, abrupt shifts between gears under normal driving conditions.
Transmission slipping or hunting between gears at highway speed.
Dark, burnt-smelling ATF fluid during a dipstick inspection.
Transmission warning light or fault codes related to pressure or shift solenoids.
Always consult the manufacturer’s recommended service interval for filter replacement. Do not wait for symptoms to appear before performing scheduled transmission maintenance.
OE Part Number: 01M 398 009
Application: Compatible 01M four-speed automatic transmissions.
Kit Contents: Transmission filter and associated sealing components.
Hydraulic Protection: Screens contaminants to maintain correct hydraulic pressure.
OE-Style Fit: Direct replacement requiring no modifications.
Service Note: Replace the pan gasket and ATF fluid during the same service interval.
Important: Four-speed 01M transmissions require different ATF fluid than five-speed units. Always confirm the correct fluid specification before servicing.
Always verify fitment by VIN before ordering.
