Stellar Automotive Group 6L50/6L80/6L90 Boost Valve Assembly fits GM

Stellar Automotive Group 6L50/6L80/6L90 Boost Valve Assembly – Compatible for GM 2006-Up

Eliminate harsh shifts, delayed engagement, and low line pressure problems with this upgraded boost valve assembly from Stellar Automotive Group.

The factory boost valve in the 6L50, 6L80, and 6L90 transmissions is a common wear item that causes sticking, leakage, and inconsistent pressure — leading to flare, slip, harsh 1-2/2-3 shifts, and premature clutch/solenoid failure. This precision-machined, hardened assembly is a direct drop-in replacement that restores stable, firm line pressure for smoother, more reliable shifts and better transmission longevity, especially in towing or performance applications.

Perfect fit for popular models including:

• Chevrolet Silverado, Tahoe, Camaro, Corvette
• GMC Sierra, Yukon
• Cadillac Escalade, CTS-V

Common symptoms this boost valve assembly resolves:

• Harsh or delayed shifts
• Flare/slip between gears
• Low line pressure codes
• Premature clutch or solenoid wear

Easy installation – drop the valve body, replace the boost valve assembly, and enjoy improved performance. Professional installation recommended.
