Detailed Description

Wix 58946 is an automatic transmission filter kit engineered around the needs of specific vehicle applications. The filter construction is designed so transmission fluid passes through the filtration media rather than around it, while the sealed assembly and application-specific sealing components support proper fluid control during service. This makes it a practical choice for routine transmission maintenance on vehicles such as the Mitsubishi Montero, Volvo 940, and Toyota Corolla.

This part cross-references ACDelco TF277 and FRAM FT1112 for the same application.
