NO.5 NO CREEP AT ALL [SJ6A-EL]

id050307801000

5 | No creep at all
DESCRIPTION | • Vehicle does not move in D range and R position when idling on a flat paved road.
POSSIBLE CAUSE | • Either engine output low or there is clutch slippage. ― Clutch burnt (C1 clutch, C4 clutch) • Line pressure low • Shift solenoid B malfunction • Shift solenoid C malfunction • Shift solenoid E malfunction • Shift solenoid G malfunction • Line pressure control solenoid malfunction • Body GND malfunction • Control valve body malfunction ― Transmission fixed in 4GR (Operation of fail-safe function) • Short or open circuit in wiring harness • Poor connection of connector • Malfunction of electronic parts of output and input system ― There is no engine torque • Torque converter malfunction ― Foreign material or water mixed in ATF ― Excessive or low amount of ATF ― TCM malfunction Note • Before following the troubleshooting steps, make sure that the Automatic Transmission On-Board Diagnostic and Automatic Transmission Basic Inspection are conducted. (See BASIC INSPECTION [SJ6A-EL].)

Diagnostic procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Does the vehicle creep in P and/or N position? | Yes | Inspect the selector lever. (See SELECTOR LEVER INSPECTION.)
No | Go to the next step.
2 | • Stop the engine. • Inspect the following solenoid: (See SOLENOID VALVE INSPECTION [SJ6A-EL].) ― Shift solenoid B ― Shift solenoid C ― Shift solenoid E ― Shift solenoid G ― Line pressure control solenoid • Are these solenoids normal? | Yes | Go to the next step.
No | Inspect the coupler component. • If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL [SJ6A-EL].) (See CONTROL VALVE BODY INSTALLATION [SJ6A-EL].)
3 | • Remove the torque converter. (See TORQUE CONVERTER REMOVAL/INSTALLATION [SJ6A-EL].) • Inspect the torque converter. • Is the torque converter normal? | Yes | Inspect the ATF condition. • If a large amount of metal specks are found, overhaul the transmission and repair or replace any malfunctioning parts. (See AUTOMATIC TRANSMISSION REMOVAL/INSTALLATION [SJ6A-EL].) (See Automatic Transmission Workshop Manual [SJ6A-EL].) • If a large amount of metal specks are not found, replace the control valve body. (See CONTROL VALVE BODY REMOVAL [SJ6A-EL].) (See CONTROL VALVE BODY INSTALLATION [SJ6A-EL].)
No | Replace the torque converter. (See TORQUE CONVERTER REMOVAL/INSTALLATION [SJ6A-EL].)
4 | • Verify test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If malfunction remains, inspect the related Service Information and perform repair or diagnosis. • If the vehicle is repaired, troubleshooting completed. • If the vehicle is not repaired or additional diagnostic information is not available, replace the TCM. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
