Torque Converter

WARNING: This page is about a different variant/trim than selected.

Pressure Regulator Valve

Line (3) fluid pressure is routed through the pressure regulator valve and into the converter feed (17) fluid circuit. Converter feed (17) fluid is routed thru orifices #21 to the TCC fault valve and thru orifice #47, 46, 45 and 22 to the TCC control valve.

VFS TCC Control Solenoid E

Controlled by the TCM, the VFS TCC control solenoid E valve regulates feed limit fluid pressure into the TCC solenoid signal (26) fluid circuit. TCC solenoid signal (26) fluid is used to control the apply and release of the torque converter clutch. TCC solenoid signal (26) fluid is directed thru orifice #33 to the TCC regulator valve, thru orifice #35 to the TCC fault valve and thru orifice #34 to the TCC control valve.

TCC Control Valve

Converter feed (17) fluid passes through the TCC control valve into the TCC release (30) fluid circuit and is routed to the torque converter assembly.

TCC Fault Valve

Converter feed (17) fluid passes through the TCC fault valve and then routed to the TCC control valve.

TCC Regulator Valve

Spring force holds the valve in the released position, thereby blocking feed limit (23) pressure from entering the regulator apply (27) fluid circuit.

Torque Converter

TCC release (30) fluid pressure is routed to the torque converter to keep the TCC released. Fluid leaves the converter in the TCC apply (29) fluid circuit and returns to the cooler feed (14) through the TCC control valve.
