EXCESSIVE SHIFT SHOCK FROM N TO D OR N TO R POSITION (GW6A-EL, GW6AX-EL) DIAGNOSTIC PROCEDURE

Step	Inspection	Results	Action
1	VERIFY MALFUNCTION SYMPTOM Is the malfunction symptom (shift shock/shifting time) at the same level compared to a vehicle of the same model?	Yes	Symptom troubleshooting is completed.
1		No	Go to the next step.
2	PERFORM ON-BOARD DIAGNOSTIC TO VERIFY HYDRAULIC PRESSURE SWITCH OPERATION PRESSURE Is the operation pressure normal?	Yes	Go to the next step.
2		No	Replace the control valve body. (See CONTROL VALVE BODY REMOVAL/INSTALLATION .)
3	PERFORM INITIAL LEARNING, N TO D POSITION LEARNING, AND N TO R POSITION LEARNING Perform the Initial Learning. (See INITIAL LEARNING .) Perform N to D position learning using the following procedure: The ATF temperature is 30 °C {86 °F} or more. Shift the selector lever from P position to N position. Shift the selector lever from N position to D position and wait for 5 s or more while holding the lever in the D position. Shift the selector lever from D position to N position and wait for 5 s or more while holding the lever in the N position. Perform the procedures (3) to (4) above ten times. Perform N to R position learning using the following procedure: The ATF temperature is 60 °C {140 °F} or more. Shift the selector lever from P position to N position. Shift the selector lever from N position to R position and wait for 5 s or more while holding the lever in the R position. Shift the selector lever from R position to N position and wait for 5 s or more while holding the lever in the N position. Perform the procedures (3) to (4) above ten times. Does the symptom disappear?	Yes	Symptom troubleshooting is completed.
3		No	Go to the next step.
4	INSPECT ENGINE CONTROL SYSTEM FOR MALFUNCTION Perform the symptom troubleshooting "FAST IDLE/RUNS ON". (See NO. 9 FAST IDLE/RUNS ON [VIN Y] .) Is there any malfunction?	Yes	Repair or replace any malfunctioning parts according to the inspection result.
4		No	Go to the next step.
5	INSPECT SIGNAL PARTS FOR MALFUNCTION Inspect the value at the following PCM PIDs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (VIN Y)] .) APP (APP sensor) RPM (CKP sensor) Is there any malfunction?	Yes	Repair or replace any malfunctioning parts according to the inspection result.
5		No	Go to the next step.
6	INSPECT ENGINE MOUNT/SUSPENSION FOR POOR TIGHTENING Is there any malfunction?	Yes	Repair or replace any malfunctioning parts according to the inspection result. (See ENGINE REMOVAL/INSTALLATION [VIN Y] .)
