Torque Converter - Released Position Only
- Pressure Regulator Valve:
-
Line pressure is routed through the pressure regulator valve and into the converter feed fluid circuit. Converter feed fluid is routed to the TCC control valve and to the TCC enable valve.
- TCC Regulator Valve:
-
Spring force holds the valve in the release position, thereby blocking line pressure from entering the regulated apply fluid circuit.
- TCC Enable Valve:
-
Converter feed fluid is routed through the TCC enable valve and into the converter FDL circuit. Converter FDL fluid is routed to the TCC control valve.
- TCC Control Valve:
-
Spring force holds the valve in the release position allowing converter feed fluid to enter the release circuit.
- Torque Converter:
-
Release fluid pressure is routed to the torque converter to keep the TCC released. Fluid leaves the converter in the apply fluid circuit and returns to the cooler through the TCC control valve.
