Features and Benefits: The redesigned TransGo hardened steel control valve features longer zones that restore the hydraulic integrity of the circuit by utilizing previously unused and therefore unworn areas of its bore. Additionally, the special valve and spring calibration allows the computer to control the regulation more precisely, which results in better slip control. Finally, the USA-made hardened steel clutch selector valves greatly help prevent the valves from sticking in their bores. Fixes/Prevents/Reduces: Shift solenoid performance codes or false P0751 due to sticking or dragged clutch selector valves Low speed surge.Cycling during cylinder deactivation.Extends converter clutch lining durability Clutch selector valve and regulator valve kit.Fits all 2006-later 6L45, 6L50, 6L80, 6L90;2006 and newer vehicles with 6L45, 6L50, 6L80, and 6L90 automatic transmissions often complain of sticking or a surge sensation, as well as shift solenoid or TFP performance codes at sticking of
