Shift Solenoid Assembly, Shift Control Solenoids 1 and 2

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

SSA/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**

SSB/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**

SSC/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**
