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.
