Lubrication Hydraulic Circuits
Lubrication for the transmission is supplied by the transmission fluid cooler return tube. Transmission fluid is sent to the transmission fluid cooler from the TCC control valve.
LINE pressure supplied to the pressure regulator valve is sent to the TCC control valve as CONV FD pressure. During TCC release, the TCC control valve sends the transmission fluid to the torque converter to release the clutch. The transmission fluid returns to the TCC control valve from the torque converter and is directed to the transmission fluid cooler on the COOLER FEED circuit.
