Line pressure fills the torque converter feed circuit with fluid up to 1103 kPa (160 psi). The torque converter feed relief valve prevents excessive pressure from reaching the torque converter. When the TCC solenoid is off, the TCC regulator valve connects the torque converter feed circuit to the torque converter release circuit, and fluid flows into the torque converter. Fluid exits the torque converter into the torque converter apply circuit. The TCC regulator valve connects the torque converter feed circuit and the torque converter apply circuit. Fluid from the torque converter flows past the torque converter anti-drain back valve and the transmission oil cooler bypass valve.

To apply the TCC, the TCC solenoid directs TCC control pressure to the TCC regulator valve, moving the valve to the left against spring pressure. The TCC regulator valve is positioned to connect the pump output to the torque converter apply circuit. Fluid in the feed circuit is directed to the torque converter and applies the TCC. Fluid exits the torque converter in the torque converter release circuit. The TCC regulator valve connects the torque converter outlet to exhaust, and fluid returns to the sump.

When the TCC regulator valve is in the TCC apply position, the torque converter feed circuit is connected to the torque converter circuit, providing continuous fluid flow to the transmission oil cooler bypass valve.
