Diagnostic Procedure

WARNING: This page is about a different variant/trim than selected.

STEP	INSPECTION		ACTION
1	VERIFY MALFUNCTION CONDITION Does the shift shock occur only when the engine is cold?	Yes	Go to the next step.
1		No	Go to Step 3.
2	INSPECT TFT SENSOR AND RELATED CIRCUIT FOR MALFUNCTION Inspect the TFT sensor and related wiring harness: vibration, intermittent open/short circuit. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION .) Is it normal?	Yes	Go to the next step.
2		No	Repair or replace part if necessary.
3	VERIFY IF MALFUNCTION CAUSE IS UN-EXECUTION OF INITIAL LEARNING PROCEDURE Perform the initial learning procedure. (See INITIAL LEARNING .) Does symptom eliminate?	Yes	Troubleshooting is completed.
3		No	Go to the next step.
4	INSPECT LINE PRESSURE Is the line pressure normal? (See MECHANICAL SYSTEM TEST .)	Yes	Go to the next step.
4		No	Repair or replace any malfunctioning parts according to the inspection results.
5	INSPECT STALL SPEED Is stall speed normal? (See MECHANICAL SYSTEM TEST .)	Yes	Go to the next step.
5		No	Repair or replace any malfunctioning parts according to the inspection results.
6	VERIFY IF MALFUNCTION CAUSE IS SHIFT SOLENOIDS OR OTHER Stop the engine. Inspect following solenoids. Line pressure control solenoid (See LINE PRESSURE CONTROL SOLENOID INSPECTION .) Shift solenoid B (See SHIFT SOLENOID B INSPECTION .) Shift solenoid C (See SHIFT SOLENOID C INSPECTION .) Shift solenoid E (See SHIFT SOLENOID E INSPECTION .) Are they normal?	Yes	Go to the next step.
6		No	Inspect the coupler component. If normal, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .)
7	VERIFY IF MALFUNCTION CAUSE IS TRANSAXLE (INCLUDING CONTROL VALVE BODY) OR ATF FLUID LEVEL Inspect the ATF condition. Are a metal specks found?	Yes	If large amount of metal specks are found, replace the transaxle. (See AUTOMATIC TRANSAXLE REMOVAL/INSTALLATION .) If a large amount of metal specks are not found, replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .)
7		No	Perform the "AUTOMATIC TRANSAXLE FLUID (ATF) LEVEL ADJUSTMENT" procedure. (See AUTOMATIC TRANSAXLE FLUID (ATF) LEVEL ADJUSTMENT .)
8	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.
