1

Vehicle does not move in D range, or in R position

DESCRIPTION

•  Vehicle does not move when AP is depressed.

POSSIBLE CAUSE

•  If the vehicle does not move in D range or R position, basically, the malfunction is in the AT. (Vehicle will move even with a malfunction in the TCM.) Since a malfunction is in the sensor circuit or output circuit is the cause of the malfunction in the AT, inspect the sensors, output circuit, and the related wiring harnesses.

1.  Clutch slipped, worn (D range-Forward clutch, R position-Direct clutch, Coast clutch, Reverse band)

•  Fluid pump malfunction

•  Shift solenoid B malfunction

•  Pressure control solenoid B malfunction

•  Pressure control solenoid C malfunction

•  Body ground malfunction

•  Control valve body malfunction

2.  Selector lever malfunction

3.  Parking mechanism not operating properly

4.  Torque converter malfunction

Note

•  Before the following the troubleshooting steps, make sure that the Automatic Transmission On-Board Diagnostic and Automatic Transmission Basic Inspections are conducted.
(See BASIC INSPECTION [5R55S].)

Diagnostic procedure

STEP	INSPECTION		ACTION
1	When the vehicle is stopped on a flat, level road and the engine is off, does the vehicle move when it is pushed? (In D range or N, R positions and brake released)	Yes	Go to the next step.
1		No	Check the parking mechanism.
2	Disconnect the TCM connector. Is the resistance between TCM ground terminal CO and body ground, and between TCM ground terminal CL and body ground less than 5.0 ohms?	Yes	Go to the next step.
2		No	Repair the open ground circuit.
3	Inspect the pressure control solenoid B and C. (See SOLENOID VALVE INSPECTION [5R55S].) Is it normal?	Yes	Clean and inspect main control, if parts are damaged replace main control. If the problem remains, overhaul the transmission and repair or replace any malfunctioning parts.
3		No	Repair or replace any malfunctioning parts.
4	• Verify test results. ― If normal, return to the diagnostic index to service any additional symptoms. ― If the malfunction remains, inspect the related Service Information and perform repair or diagnosis. • If the vehicle repaired, the troubleshooting is completed. • If the vehicle the not repaired or additional diagnostic information is not available, replace the TCM.
