Line pressure fills the converter feed circuit with fluid up to 1, 130 kPa (160 psi). The converter feed blow off valve prevents excessive pressure from reaching the torque converter. When the TCC solenoid is commanded off, the TCC regulator valve connects the converter feed circuit to the converter release circuit and fluid flows into the torque converter. Fluid exits the torque converter in the converter apply circuit.
