Stellar Automotive Group 4T65E 3rd Clutch Piston fits GM

Stellar Automotive Group 4T65E 3rd Clutch Molded Piston – Compatible for GM 1997-2005

Stop slipping in 3rd gear, delayed upshifts, and burnt 3rd clutches with this upgraded molded 3rd clutch piston from Stellar Automotive Group.

This direct-replacement piston is the critical apply component for the 3rd clutch pack in all 4T65E transmissions. The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens 3rd gear apply — leading to flare on 2-3 upshifts, slipping under load, and rapid clutch failure. This molded piston with permanently bonded rubber seal restores full line pressure, delivers crisp 2nd-to-4th transitions, and protects your 3rd clutch pack for reliable daily driving or light towing.

Perfect fit for popular models including:

• Chevrolet Impala, Monte Carlo, Lumina
• Buick Regal, LeSabre, Century
• Oldsmobile Intrigue, Aurora
• Pontiac Grand Prix

Symptoms of a failing 3rd clutch piston:

• Flare or slip on 2-3 upshift
• Delayed engagement in 3rd gear
• Harsh shifts when clutches finally grab
• Burnt 3rd frictions on teardown

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