Stellar Automotive Group 4L40E/5L40E Forward Clutch Molded Piston – Compatible for GM & BMW 2000-2010
Stop delayed forward movement, slipping on takeoff, and burnt forward clutches with this upgraded molded forward clutch piston from Stellar Automotive Group.
This direct-replacement piston is the critical apply component for the forward clutch pack in all 4L40E and 5L40E transmissions. The factory piston commonly cracks or loses its bond under heat and mileage, causing internal leakage that weakens forward apply — leading to no drive, harsh engagement, and rapid clutch failure. This molded piston with permanently bonded rubber seal restores full line pressure, delivers instant forward engagement, and protects your forward clutch pack for reliable daily driving or light towing.
Perfect fit for popular models including:
Chevrolet Trailblazer, SSR
BMW 3 Series (E46), 5 Series (E39)
Cadillac CTS (early), Escalade (select)
Symptoms of a failing forward clutch piston:
Delayed or no forward movement
Slipping or flare on takeoff
Harsh engagement when it finally grabs
Burnt forward frictions on teardown
Don't let a $50 piston destroy a $500 clutch pack — install the Stellar Automotive Group molded forward piston and get moving strong from the start.
Note: All parts are distributed, not designed or manufactured, by Stellar Automotive Group.
