STEP	INSPECTION		ACTION
1	INSPECT LINE PRESSURE Is the line pressure normal? (See MECHANICAL SYSTEM TEST .)	Yes	Go to the next step.
1		No	Repair or replace any malfunctioning parts according to the inspection results.
2	VERIFY SHIFT POSITION Is shift point normal? (See ROAD TEST .)	Yes	Go to the next step.
2		No	Go to No.9 "ABNORMAL SHIFTING".
3	INSPECT SHIFT SOLENOIDS CONTROL CIRCUIT FOR MALFUNCTION Inspect the coupler component for open or short. Are coupler component normal?	Yes	Go to the next step.
3		No	Replace the coupler component.
4	INSPECT SHIFT SOLENOIDS FOR MALFUNCTION Stop the engine. Inspect following solenoids. Shift solenoid C (See SHIFT SOLENOID C INSPECTION .) Shift solenoid D (See SHIFT SOLENOID D INSPECTION .) Shift solenoid E (See SHIFT SOLENOID E INSPECTION .) Line pressure control solenoid (See LINE PRESSURE CONTROL SOLENOID INSPECTION .) TCC control solenoid (See TORQUE CONVERTER CLUTCH (TCC) CONTROL SOLENOID INSPECTION .) Shift solenoid F (See SHIFT SOLENOID F INSPECTION .) Are they normal?	Yes	Go to the next step.
4		No	Replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .)
5	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 .)
5		No	Perform the "AUTOMATIC TRANSAXLE FLUID (ATF) LEVEL ADJUSTMENT" procedure. (See AUTOMATIC TRANSAXLE FLUID (ATF) LEVEL ADJUSTMENT .)
6	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.
