Circuit/System Description

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

Pressure control solenoid Valve 2 is part of the control solenoid valve assembly which has no serviceable components. The normally low pressure control solenoid Valve 2 regulates and directs fluid pressure to the 3-5 reverse clutch regulator valve. Increasing pressure control solenoid valve 2 pressure increases pressure to the 3-5 reverse clutch. The transmission control module (TCM) varies the current to the pressure control solenoid Valve 2 by controlling the amount of time the low side driver is ON and OFF. Increasing the current to the pressure control solenoid Valve 2 increases pressure control solenoid Valve 2 fluid pressure by closing OFF the solenoid valve exhaust port. Decreasing the current to the pressure control solenoid Valve 2 decreases clutch pressure control solenoid Valve 2 fluid pressure by opening the solenoid valve exhaust port. Power to pressure control solenoid Valve 2 is supplied by the TCM through a high side driver. The high side driver protects the circuit and components from excessive current flow. If excessive current flow is detected, the high side driver will turn OFF. When the fault is corrected, the high side driver will reset.
