Country/Region of Manufacture: United StatesManufacturer Part Number: 6L8-BOOST-OESOther Part Number: T104741R-1Brand: TransgoManufacturer Warranty: YesStock OE Replacement Boost Valve Assembly Fits all 6L45, 6L50, 6L80, 6L90 2007-18 2006 and newer General Motors and BMW vehicles equipped with 6L45, 6L50, 6L80 and 6L90 automatic transmissions often wear out the line pressure boost valve and bushing. As a result, the transmission will not have the required main line pressure boost under load. The computer tailors the line pressure rise in accordance with the calculated load. It does this by varying the pressure control solenoid current, which in turn varies the EPC solenoid pressure output. The pressure control solenoid output then acts on the boost valve, which in turn acts on the pressure regulator valve to raise the main line pressure accordingly. Adequate main line pressure rise is required to provide enough clamping force under all load conditions to prevent slipping,
