Stellar Automotive Group U240/U241/U250 Underdrive Piston Retainer fits Toyota

Stellar Automotive Group U240/U241/U250 Underdrive Piston Retainer (4.160” O.D.) – Compatible for Toyota & Lexus 1998-Up

Stop slipping in 1st & 2nd gears, delayed takeoff, and burnt underdrive clutches with this precision bonded retainer from Stellar Automotive Group.

This direct-replacement retainer (4.160” outer diameter) secures the underdrive clutch piston and return spring in perfect alignment. The factory retainer commonly warps or loses its bond under heat and mileage, causing internal leakage that weakens underdrive apply — leading to no forward movement, harsh engagement, and rapid clutch failure. This upgraded bonded steel retainer with permanently bonded rubber seal restores full line pressure, delivers instant takeoff power, and protects your underdrive clutch pack for reliable daily driving or light towing.

Perfect fit for popular models including:

• Toyota Camry, Highlander, RAV4, Sienna, Solara
• Lexus RX300

Symptoms of a failing underdrive retainer:

• Delayed or no forward movement
• Slipping or flare on takeoff
• Harsh engagement when it finally grabs
• Burnt underdrive frictions on teardown

Don’t let a warped retainer cost you an entire clutch pack — install the Stellar Automotive Group bonded underdrive retainer and get moving strong from the start.
