Transgo Stock OE Replacement Boost Valve Assembly for 6L45, 6L50, 6L80, 6L90 (2006-ON)
For 2006 and later models of General Motors and BMW vehicles equipped with 6L45, 6L50, 6L80, and 6L90 automatic transmissions, the line pressure boost valve and sleeve are prone to wear. When these components deteriorate, the transmission fails to maintain the necessary main line pressure boost under load, leading to shifting issues and potential damage.
The vehicle's computer system adjusts the line pressure based on load by varying the pressure control solenoid current, which modifies the EPC solenoid pressure output. This output then influences the boost valve, which controls the pressure regulator valve to increase main line pressure accordingly.
Adequate main line pressure is critical to ensuring enough clamping force under various load conditions, preventing slippage and ensuring smooth shifts. A worn boost valve can cause issues like soft or flare shifts, burnt frictions, and damage to the lock-up clutch. These issues are often accompanied by multiple gear ratio, shift, and solenoid performance codes.
