  • Keeps fluid clean: Designed to filter the transmission fluid that serves as the lifeblood of your transmission.
  • Protects vital components: Helps keep debris from normal wear and tear from reaching and clogging the valve body and other internal parts.
  • Routine service part: Replacing the filter as part of regular service helps extend transmission life and reduce the chance of avoidable, costly repairs.

Every transmission eventually accumulates debris, so a fresh filter is a smart part of scheduled maintenance. Install it during a fluid-and-filter service following the vehicle's service procedure. Country of origin: Taiwan.
