Stellar Automotive Group 6T40 4-5-6 Clutch Drum (4 Clutch, 36 Lugs) fits GM

Stellar Automotive Group 6T40 4-5-6 Clutch Drum (4 Clutch, 36 Outer Lugs for 3-5 Rev) – Compatible for GM

This new 6T40 4-5-6 clutch drum (4 clutch, 36 outer lugs for 3-5 reverse compatibility) from Stellar Automotive Group is a direct replacement for failed or burnt units in Gen 1 6T40/6T45 transmissions.

This direct-replacement drum (4 clutch capacity, 36 outer lugs designed for 3-5 Rev compatibility) is a precise fit for the 6T40/6T45 transmissions. The factory drum often suffers spline wear or distortion under torque, causing clutch slip, flare on upshifts, and eventual pack failure. This upgraded drum provides superior spline engagement, strength, and durability — ideal for stock rebuilds, high-mileage repairs, or light performance upgrades.

Perfect fit for popular models including:

• Chevrolet Malibu, Equinox, Traverse
• Buick LaCrosse, Regal, Encore
• GMC Terrain

Common symptoms this drum resolves/prevents:

• Slip or flare on 4-5 or 5-6 upshift
• Delayed engagement in higher gears
• Burnt 4-5-6 clutches on teardown
• Spline wear or drum distortion

Easy installation – replace during clutch pack rebuild. Professional installation recommended.
