The automatic transmission filter removes debris and clutch-material particles from the fluid circulating through compatible 01M four-speed automatic transmissions. Clean fluid helps the valve body and internal hydraulic circuits operate consistently, supporting correct shift quality and component lubrication.
A restricted filter can limit fluid flow and reduce available hydraulic pressure. Replace the filter as part of scheduled transmission service or whenever the transmission pan is removed for repair.
Automatic transmissions rely on clean, correctly specified fluid to control shift solenoids, clutch packs, and hydraulic passages. As the filter collects contaminants, it can become restricted and affect fluid circulation.
Replacing the filter during routine service helps protect the valve body and internal transmission components from debris. It also gives you an opportunity to inspect the removed fluid and transmission pan for signs of abnormal internal wear.
Inspect the transmission and service the filter if you notice:
Delayed engagement when selecting Drive or Reverse.
Rough, inconsistent, or delayed gear changes.
Darkened or contaminated automatic-transmission fluid.
Restricted fluid flow caused by a clogged filter.
Debris or friction material found in the transmission pan.
A transmission pan gasket replacement already being performed.
Diagnose shifting concerns carefully, as low fluid level, incorrect fluid, solenoid faults, valve-body wear, and internal transmission damage can produce similar symptoms.
OE Part Number: 01M 325 429
Function: Filters automatic-transmission fluid before it circulates through internal hydraulic components.
Application: For compatible 01M four-speed automatic transmissions.
Service Component: Intended for replacement during transmission fluid and pan-gasket service.
Hydraulic Protection: Helps reduce the circulation of harmful particles through the valve body and transmission.
OE-Style Fit: Designed for correct installation in the transmission filter location.
Always verify fitment by VIN before ordering.
