Stellar Automotive Group U150/U151/U250 Overdrive Clutch Outer Piston fits Toyota

Stellar Automotive Group U150/U151/U250 Overdrive Clutch Outer Piston (Bonded) – Compatible for Toyota & Lexus 2002-Up

Stop slipping in 4th-5th gears, delayed upshifts, and burnt overdrive clutches with this precision bonded outer piston from Stellar Automotive Group.

This direct-replacement piston is the critical outer apply component for the overdrive clutch pack in all U150, U151, and U250 transmissions. The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens overdrive apply — leading to flare on upshifts, slipping under load, and rapid clutch failure. This upgraded molded piston with permanently bonded rubber seal restores full line pressure, delivers crisp 4th-to-5th transitions, and protects your overdrive clutch pack for reliable daily driving or light towing.

Perfect fit for popular models including:

• Toyota Highlander, Camry, RAV4, Sienna
• Lexus RX350, ES350

Symptoms of a failing overdrive outer piston:

• Flare or slip on 4-5 upshift
• Delayed engagement in overdrive
• Harsh shifts when overdrive grabs
• Burnt overdrive frictions on teardown

Don’t let a $50 piston destroy a $500 clutch pack — install the Stellar Automotive Group bonded overdrive outer piston and shift strong through every gear.
