No creep at all

DESCRIPTION

• Vehicle does not move in D 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 ground 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

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

• Inspect the ATF condition.

  (See AUTOMATIC TRANSMISSION FLUID (ATF) INSPECTION [SJ6A-EL].)

• Are there any metal specks found in ATF?

Yes

• 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 Bulletins and/or On-line Repair 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].)
