U660E Direct Clutch Bonded Piston fits Toyota Lexus

Stellar Automotive Group U660E Direct Clutch Bonded Piston (2.665" ID, 8 Lugs/4 Slots) – Compatible for Toyota & Lexus 2007-ON

Stop slipping in 3rd through 6th gears and burnt direct clutches with this precision bonded C2 direct clutch piston from Stellar Automotive Group.

This direct-replacement piston is machined from durable aluminum with a permanently bonded rubber sealing lip, featuring the exact 2.665" inner diameter and 8-lug/4-slot design to match OEM specs perfectly. Original direct pistons often crack or lose their bond under high torque, causing internal leakage that destroys the C2 clutch pack and triggers harsh shifts or no apply in higher gears. Installing this upgraded bonded piston during your U660E rebuild restores full hydraulic pressure, delivers smooth and positive engagement, and keeps your transmission strong for the long haul.

Fits popular U660E-equipped models including:

• Toyota Camry, Solara, Highlander, RAV4, Venza, Avalon, Sienna (2007-2022)
• Lexus ES350, RX350, RX450h (2007-2018)
• Most 6-speed FWD Toyota/Lexus applications

Symptoms of a failing direct clutch piston:

• Slipping or flare on 3-4, 4-5, or 5-6 upshifts
• Harsh engagement or shudder in higher gears
• Burnt direct (C2) clutches during teardown
• Delayed or no apply in 3rd-6th

Don’t let a cracked piston cost you another clutch pack — upgrade to the Stellar Automotive Group bonded direct piston and rebuild with confidence.
