Shift Solenoid Assembly, Shift Control Solenoids 1 and 2

DESCRIPTION
Three ON/OFF solenoids are used for electronic shift scheduling. They are Shift Solenoid Assemblies (SS1, SS2, SS3). The three solenoids are located in the main control valve body. The solenoids are two-way, normally open style. Solenoids SS1, SS2, and SS3 provide gear selection of 1st through 4th by controlling the pressure of the three shift valves and the forward clutch control valve.

SS1
Symptoms
Improper gear selection depending on failure mode and gearshift lever position.
- Failed ON - 3rd gear only.
- Failed OFF - 1st and 2nd gear only.

DTCs
P0731**, P0732**, P0733**, P0734**, P0750*, P0751**, P1751**

SS2
Symptoms
Improper gear selection depending on failure mode and gearshift lever position.
- Failed ON - 1st and 4th gear only.
- Failed OFF - 2nd and 3rd gear only.

DTCs
P0731**, P0733**, P0734**, P0755*, P0756**, P1756**

SS3
Symptoms
Improper gear selection depending on failure mode and gearshift lever position.
- Failed ON - No engine braking.
- Failed OFF - No 4th gear.

DTCs:
P0734**, P0760*, P0761*, P1761**

** May also be generated by some non-electrical transaxle component condition.
* Output circuit check, generated only by electrical conditions.
