Torque Converter Hydraulic Circuit Diagram (TCC Released)
WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
To apply the TCC, the TCC solenoid applies regulated solenoid pressure to the TCC charge control valve and the TCC apply regulator valve to move the valves. Line pressure is supplied by the manual control valve to the TCC apply regulator valve through the NDX circuit. As the TCC apply regulator valve moves, it opens the NDX circuit to supply the CAPY circuit with regulated line pressure to apply the TCC.
Line pressure is supplied to the TCC apply regulator valve. The TCC apply regulator valve directs regulated line pressure to the TCC through the CAPY circuit to apply the TCC. CAPY also supplies regulated line pressure to the opposite side of the TCC apply regulator valve for controlled TCC engagement.
