Ford vehicles equipped with CFT30 transmissions may exhibit TCC problems such as shudder, slipping, overheated fluid and failed clutch lining. TCC codes can accompany these issues or set before symptoms are noticed. Reconditioning the bore and installing Sonnax oversized TCC apply valve 33740-06 restores hydraulic integrity to the circuit for revived TCC operation and control. The hardcoat anodized aluminum valve combats premature wear.
