WIX Automatic Transmissi on Filter Kit

The WIX Automatic Transmission Filter Kit (model 58658) is a purpose-engineered racing filter assembly designed specifically for Mopar TorqueFlite transmissions. As an experienced mechanic, you know that transmission fluid degradation is one of the leading causes of shifting lag, heat buildup, and premature wear in automatic gearboxes. This complete kit delivers OEM-spec filtration with upgraded media to extend fluid life and maintain hydraulic pressure consistency—critical for vehicles pushing higher power outputs or experiencing repetitive towing and high-demand driving cycles.

WIX Racing Filters engineered this kit with a premium synthetic media blend that captures finer particulates than standard replacements, protecting valve bodies and clutch packs from microscopic debris that accumulates over service intervals. The assembly includes the filter element and gasket—both critical wear items—eliminating the need to source components separately and ensuring consistent seal integrity across the pan-to-case interface. The compact 7.12 x 2.12 x 8.12-inch profile fits within OEM mounting dimensions, maintaining stock clearances while delivering measurably higher contaminant capacity and flow characteristics suited to racing and performance applications.

Builders upgrading TorqueFlite-equipped vehicles—whether classic Mopars, high-performance street machines, or competition platforms—benefit most from this kit during transmission service, especially after extended intervals or fluid contamination events. Installation is straightforward: remove the transmission pan, unbolt the stock filter assembly, and bolt on the WIX unit using existing holes; no modifications or adapters required. For shops rotating multiple vehicles through service bays, keeping this kit stocked eliminates downtime waiting for special orders while guaranteeing OEM fitment and performance restoration on every Mopar TorqueFlite application.
