Line Pressure Hydraulic Circuits (Shown with the Manual Valve in the DRIVE Position)
Line Pressure Hydraulic Circuits
The PCM controls line pressure with the LPC solenoid. This affects shift feel and apply component operation.
When the engine is running, the pump supplies pressure to the pressure regulator valve, which is controlled by the LPC solenoid. The pressure regulator valve controls the line pressure.
The line pressure circuit supplies the manual valve. The manual valve directs the line pressure to either the REV/REV SUPPLY circuit when the manual control lever is in the REVERSE position or the DRIVE 1 circuit when the manual control lever is in the DRIVE or LOW position.
Lubrication Circuits (Torque Converter Clutch (TCC) Released)
Lubrication Circuits (Torque Converter Clutch [TCC] Applied)
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.
Torque Converter Hydraulic Circuits (Torque Converter Clutch [TCC] Applied)
Torque Converter Hydraulic Circuits
The PCM controls the TCC solenoid. The TCC solenoid applies hydraulic pressure to the TCC control and regulator apply valves through the TCC SOL SIG circuit. Regulated DRIVE 2 pressure from the multiplex shift valve is directed to the TCC control valve by the TCC regulator apply valve through the REG APPLY circuit. The TCC control valve directs pressure from the REG APPLY circuit to the TCC APPLY circuit to apply the clutch.
The transmission fluid returns to the TCC control valve through the TCC RELEASE hydraulic circuit. The TCC control valve opens the TCC RELEASE circuit to exhaust, so the TCC RELEASE circuit is not pressurized when the TCC is applied.
Torque Converter Hydraulic Circuits (Torque Converter Clutch [TCC] Released)
When the TCC is released, The TCC solenoid does not apply hydraulic pressure to the TCC control or regulator apply valves. The TCC control valve, in this position, directs hydraulic pressure from the CONV FD circuit to the torque converter through the TCC RELEASE hydraulic circuit and it returns to the TCC control valve through the TCC APPLY circuit.
Solenoid Hydraulic Circuits
Solenoid Hydraulic Circuits
LINE pressure from the pump is directed to the individual shift, TCC and LPC solenoids by the solenoid regulator valve on the SOL FEED circuit. The solenoids, controlled by the PCM, direct the fluid to the valves that they control.
The LPC solenoid sends varying pressure to the line pressure regulator valve to control line pressure.
