Raider 2WD V6-3.7L (2008)
Shift Solenoid: Description and Operation
Switch Valve - Solenoid
SWITCH VALVE - SOLENOID
DESCRIPTION
The Solenoid Switch Valve (SSV) is located in the main valve body and directs the output from the L/R-TCC solenoid to either the L/R clutch or the
TCC control valves
OPERATION
The Solenoid Switch Valve controls line pressure from the LR-TCC solenoid. In 1st gear, the SSV will be in the downshifted position, thus directing
fluid to the L/R clutch circuit. In 2nd, 3rd, 4th, and 5th gears, the solenoid switch valve will be in the upshifted position and directs the fluid into the
torque converter clutch (TCC) circuit.
When shifting into 1st gear, a special hydraulic sequence is performed to ensure SSV movement into the downshifted position. The L/R pressure
switch is monitored to confirm SSV movement. If the movement is not confirmed (the L/R pressure switch does not close), 2nd gear is substituted for
1st. A DTC will be set after three unsuccessful attempts are made to get into 1st gear in one given key start.
