Shift Solenoid 4
Shift solenoid 4 (Lube Boost) is commanded ON based on torque and temperature inputs to the HPCM. When required, shift solenoid 4 is energized ON, allowing line fluid to enter the solenoid 4 signal circuit. Solenoid 4 signal fluid is then routed through orifice #4 to the lube regulator valve elevating lube and motor cooling pressure and flow.
