Solenoid Switch Valve Latched In TCC Position

1995 Chrysler Cirrus L4-148 2.4L DOHC VIN X MFISECTION Solenoid Switch Valve Latched In TCC Position
THEORY OF OPERATION:
The Solenoid Switch Valve (SSV) controls the direction of the transmission fluid when the L-R/TCC solenoid 'is energized. SSV will be in the downshifted position in 1st gear, thus directing the fluid to the L-R clutch circuit. In 2nd, 3rd, and 4th, it will be in the upshifted position and directs the fluid into the Torque Converter Clutch (TCC).

When shifting into 1st gear, a special hydraulic sequence is preformed 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.

This code is set if three consecutive unsuccessful attempts are made to get into 1st gear in one given key start.

LIMP-IN:
NO

WHEN MONITORED/SET CONDITIONS:
During an attempt shift into 1st gear.

TRANSMISSION EFFECTS:
All model years and calibrations.

Transmission will have no 1st gear (2nd gear will be substituted), and no EMCC operation.

POSSIBLE CAUSES:
- Defective TCM
- PRNDL indicates a valid OD code in the hydraulic reverse position
- Valve body - Solenoid valve stuck in TCC position
- High idle speed
- Solenoid malfunction - L-R pressure switch will not close
- L-R Pressure Switch Sense circuit shorted to battery
- Defective TCM
