Clutch cntrl valve K1 TF60, C1 TF80

Clutch cntrl valve K1 TF60, C1 TF80 • Valve • Spring Fits C1 clutch control bore for TF-80SC & TF-81SC. Fits K1 clutch control bore for TF-60SN (09G, 09K, 09M, BMW 6F21WA). Also fits Volvo (AM6), Opel (AF40), Saab (AF40/6), Ford (AF21) and Mazda (AW6A-EL). C1/K1 clutches in Aisin AW 6-speed units are applied in first through fourth gears in conjunction with other clutch packs. As the C1/K1 clutch control valve oscillates and strokes over time, bore deterioration results, which prevents proper hydraulic control of the clutch pack. This can cause flares, slipping, erratic clutch apply timing, ratio codes, and burnt C1/K1 clutches. Reconditioning the bore and installing Sonnax oversized C1/K1 clutch control valve kit 15741-55K restores normal shift operation by re-establishing the hydraulic integrity of the C1/K1 circuit. • Annular grooves help center valve in bore to reduce future side-load wear • New spring matches OE calibration • Hardcoat anodized aluminum valve combats premature wear Required tool: F-15741-TL55
