Stellar Automotive Group 6T40/6T45 Pump Seal (0.300" Thick w/ Short Flange) – Compatible for GM 2008-Up

Stop low line pressure, delayed engagement, and pump-related failures with this upgraded pump seal from Stellar Automotive Group.

This direct-replacement seal is engineered specifically for the front pump in 6T40 and 6T45 transmissions (0.300" thickness with short flange). The factory seal often hardens, shrinks, or leaks over time, causing pressure loss, slipping clutches, harsh shifts, and eventual transmission damage. This molded seal with bonded rubber provides a reliable, leak-proof fit, restores full pump pressure, and protects the pump bushing and internals for smooth, consistent performance.

Perfect fit for popular models including:

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

Common symptoms this seal resolves:

• Delayed or no forward/reverse engagement
• Low line pressure or slipping clutches
• Harsh shifts or flare between gears
• Pump bushing wear or noise on teardown

Easy installation – replace during pump service or rebuild. Professional installation recommended for best results.
