Circuit/System Description

The clutch pressure control (PC) solenoid 2 is part of the control solenoid (w/body and TCM) valve assembly and is not serviced separately. PC solenoid 2 controls transmission fluid pressure to the hybrid direct, 2-3-4 clutch regulator valve. When PC solenoid 2 is commanded ON, the TCM compares the known transmission fluid pressure (TFP) switch 3 state with the actual TFP switch 3 state. Depending one the commanded mode or gear, the clutch PC solenoid 2 controls fluid pressure to the following components:

In the ON position, PC solenoid 2 controls transmission fluid to the following components:

• EVT 1 mode, oil is supplied to drive motors 1 and 2 for cooling and the hybrid low, 1-2 clutch.
• EVT 2 mode, oil is supplied to drive motors 1 and 2 for cooling and the hybrid direct, 2-3-4 clutch.
• Gear 1, oil is supplied to the hybrid low, 1-2 clutch and the 1-3 clutch.

In the ON position, PC solenoid 2 controls the transmission fluid to the following components:

• Gear 2, oil is supplied to the hybrid low, 1-2 clutch and the hybrid direct, 2-3-4 clutch.
• Gear 3, oil is supplied to the hybrid direct, 2-3-4 clutch and the 1-3 clutch.
• Gear 4, oil is supplied to the hybrid direct, 2-3-4 clutch and the 4th clutch.
