Circuit/System Description

The shift solenoid (SS) 2 is part of the control solenoid valve assembly which has no serviceable parts. SS 2 is a normally closed (NC) ON/OFF solenoid and is controlled by the TCM through a low side driver. When the SS 2 is energized (ON), SS 2 fluid pressure is directed to the clutch select valve 3. Power to the SS 2 is supplied by the TCM through a high side driver (HSD). The HSD protects the circuit and components from excessive current flow. If excessive current flow is detected, the HSD will turn OFF. When the fault is corrected, the HSD will reset.
