Torque Converter Cooler & Lube

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

Pressure Regulator Valve

Line pressure at the valve forces fluid through the converter feed circuit which then routes the fluid to the converter clutch feed limit valve. Fluid passes through the valve and enters the TCC feed limit circuit. The limited fluid amount is then routed through orifice #29 and enters the orificed feed limit passage. The limited fluid amount is also routed to the TCC enable valve and to the converter clutch control valve.

TCC Enable Valve

Spring force holds the TCC enable valve in the downshifted position. This allows a limited fluid amount to pass through the valve and enter the orificed TCC exhaust enable circuit. Orificed TCC exhaust enable fluid then routes to the converter clutch control valve.

Converter Clutch Control Valve

Spring force holds the Converter Clutch Control valve in the downshifted position. Orificed TCC exhaust enable fluid routes to the spring end of the valve and through orifice #35, where the fluid enters the TCC exhaust enable circuit. At the same time, a limited fluid amount routes through the valve and enters the converter release circuit.

Torque Converter

Converter release fluid routes to the cover side of the TCC pressure plate, keeping the pressure plate in the released position. The fluid which is released from the converter passes around the plate and enters the converter apply circuit. This routes the fluid back to the converter clutch control valve.

Converter Clutch Control Valve

Converter apply fluid routes through the valve, through the transmission cooler, and into the lube circuits through the transmission.
