Repair And Rebuild Use

Use this module when transmission teardown identifies worn, glazed, heat-damaged, or burnt friction plates. Friction plates should be replaced only after the cause of the failure has been diagnosed. Inspect the mating steel plates, pressure plates, clutch drums, pistons, seals, valve body, fluid condition, and cooling system before completing the rebuild.

This listing is for a friction module only. It is not a complete overhaul kit and does not indicate that steel plates, gaskets, seals, pistons, filters, or other transmission components are included.

Fitment Notice

Confirm that the transmission is a U660E before ordering. Match the original friction plate count, clutch location, transmission configuration, and physical dimensions during teardown. Toyota and Lexus vehicle make, model, and year alone are not sufficient to confirm fitment.

Fluid Service Guidance

Use the vehicle manufacturer’s specified automatic transmission fluid. Lubegard ATF Protectant may be used during fluid service only when compatible with the required ATF and used according to its product directions. It is not a substitute for correcting worn or damaged transmission components.
