ATP Automotive B-217 Automatic Transmission Filter Kit for Chrysler/Dodge NAG1 Transmissions with 7.875-Inch Filter

Product overview

ATP Automotive’s B-217 transmission filter kit is engineered for Chrysler and Dodge vehicles using the NAG1 transmission. It features a 7.875-inch filter cartridge that aligns with OE standards for both particle filtration and fluid flow. This careful matching helps ensure the transmission fluid moves consistently to critical components, supporting smooth operation as the engine and transmission cycle through gears.

Debris and wear particles are a natural part of transmission life. A clean, properly sealed filter helps the fluid stay free from contaminants that could affect valve body performance and overall reliability. Replacing the filter at regular service intervals is a prudent maintenance step that may help keep the transmission operating closer to its designed behavior and reduce the likelihood of unexpected downtime.
