Federal Mogul TH700-R4/4L60E 3rd and 4th Clutch Piston fits GM

Federal Mogul TH700-R4/4L60E 3rd & 4th Clutch Molded Piston – Compatible for GM 1982-Up

Stop slipping in 3rd & 4th gears, delayed upshifts, and burnt 3-4 clutches with this upgraded molded piston from Stellar Automotive Group.

This direct-replacement piston is the critical apply component for the 3rd & 4th clutch pack in all TH700-R4 and 4L60E transmissions. The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens 3rd/4th apply — leading to flare on upshifts, slipping under load, and rapid clutch failure. This molded piston with permanently bonded rubber seal restores full line pressure, delivers crisp 3rd-to-4th transitions, and protects your clutch pack for reliable daily driving or performance use.

Perfect fit for popular models including:

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

Symptoms of a failing 3rd & 4th clutch piston:

• Flare or slip on 3-4 upshift
• Delayed engagement in 3rd/4th gear
• Harsh shifts when clutches finally grab
• Burnt 3rd/4th frictions on teardown

Don’t let a $50 piston destroy a $500 clutch pack — install the Stellar Automotive Group molded 3rd & 4th piston and shift strong through every gear.
