Federal Mogul 4L60E Overrun Clutch Piston fits GM

Federal Mogul 4L60E Overrun Clutch Piston – Compatible for GM 1993-Up

Stop engine runaway in 1st & 2nd gears and burnt overrun clutches with this precision molded overrun clutch piston from Stellar Automotive Group.

This direct-replacement piston is the critical apply component for the overrun clutch pack in all 4L60E transmissions. The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens overrun apply — leading to no engine braking, high RPM overrun when decelerating, and rapid clutch failure. This upgraded molded piston with permanently bonded rubber seal restores full line pressure, delivers smooth engine braking in lower gears, and protects your overrun clutch pack for reliable daily driving or light towing.

Perfect fit for popular models including:

• Chevrolet Silverado, Tahoe, Suburban, Camaro, Corvette
• GMC Sierra, Yukon
• Cadillac Escalade

Symptoms of a failing overrun clutch piston:

• Engine revs freely when coasting in 1st or 2nd gear
• No engine braking in lower gears
• Ratcheting noise or slipping on overrun
• Burnt overrun frictions on teardown

Don’t let a $50 piston destroy your overrun pack — install the Stellar Automotive Group molded overrun piston and feel the engine braking return instantly.

Note: All parts are distributed, not designed or manufactured, by Stellar Automotive Group.
