Stellar Automotive Group U540E Input Clutch Bonded Piston fits Toyota Lexus

Stellar Automotive Group U540E Input Clutch Bonded Piston – Compatible for Toyota & Lexus 2005-2018

Revive smooth 3rd and 4th gear performance in your U540E transmission with this high-quality bonded input clutch piston (C3) from Stellar Automotive Group.

This precision aluminum piston features a permanently bonded rubber sealing lip that matches OEM specifications exactly. Over time, original input pistons crack or lose their bond, causing internal leakage, clutch slippage, and eventual failure of the C3 clutch pack. Replacing it with this upgraded bonded version during your rebuild restores full line pressure to the input clutch, eliminates slipping in higher gears, and delivers crisp, reliable shifts for thousands of miles.

Fits popular U540E-equipped models including:

• Toyota Tacoma (2005-2015)
• Toyota Highlander & Highlander Hybrid (2008-2018)
• Toyota RAV4 (2006-2012)
• Toyota Sienna (2007-2010)
• Lexus RX330, RX350, RX400h (2004-2009)

Symptoms of a failing input clutch piston:

• Slipping or flare in 3rd or 4th gear
• Harsh or delayed upshifts
• Burnt input (C3) clutches on teardown
• Low C3 pressure during testing

Don’t let a $60 piston destroy a $600 clutch pack — install the Stellar Automotive Group bonded input clutch piston and rebuild with confidence.
