Stellar Automotive Group U340E/U341E Forward Clutch Outer Piston fits Toyota

Stellar Automotive Group U340E/U341E Forward Clutch Outer Piston (Bonded) – Compatible for Toyota & Lexus 2000-Up

Stop delayed forward movement, slipping on takeoff, and burnt forward clutches with this precision bonded outer piston from Stellar Automotive Group.

This direct-replacement piston is the critical outer apply component for the forward clutch pack in all U340E and U341E transmissions. The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens forward apply — leading to no drive, harsh engagement, and rapid clutch failure. This upgraded molded piston with permanently bonded rubber seal restores full line pressure, delivers instant forward engagement, and protects your forward clutch pack for reliable daily driving or light towing.

Perfect fit for popular models including:

• Toyota Corolla, Matrix, Celica, Scion tC
• Pontiac Vibe

Symptoms of a failing forward outer piston:

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

Don’t let a $50 piston destroy a $500 clutch pack — install the Stellar Automotive Group bonded forward outer piston and get moving strong from the start.
