Product Details

ATP Parts B-140 is built for Subaru transmission maintenance where fluid cleanliness matters.

Regular filter replacement is a practical service step for extending transmission life and reducing the chance of avoidable repair work. This part cross-references Dorman - HELP 15904 for the same application.

The ATP Premium Replacement line focuses on service parts that match the needs of common repair and maintenance jobs. For Subaru Impreza, Legacy, and Forester owners, B-140 provides a direct-fit service solution for select 1990-1999 automatic transmission applications.
