11. Disconnect the shift solenoid harness connector at the transmission housing.

12. Check for continuity between shift solenoid harness connector terminal No. 3

and body ground.

Is there 12-25 ohm ?

YES: Repair open in the wire between PCM connector terminal C3
and the shift solenoid harness connector, then go to step 13.

NO: Check shift solenoid valve E, and check for an open in the shift
solenoid harness in the transmission (see SHIFT SOLENOID VALVE
TEST ). Replace shift solenoid valve E and/or shift solenoid harness,
then go to step 13.

1. Warm up the engine to normal operating temperature (the radiator fan comes on).

2. Check to be sure that the transmission is filled to the proper level, and check for fluid leaks.

3. Drain the ATF (see DRAINING & REFILLING ) through a strainer. Inspect the ATF and strainer for

metal debris or burnt fluid.

Has the ATF deteriorated?

YES: Replace ATF (see DRAINING & REFILLING ), and go to step 4.

NO: Go to step 8 .

4. Clear the DTC with the HDS.

5. Test-drive the vehicle in the D position in all five gears at speeds over 12 mph (20 km/h) for more than 20

seconds, then slow down to a stop.

6. Retest-drive the vehicle in the D position in all five gears at speeds over 12 mph (20 km/h) for more than

20 seconds, then slow down to a stop.

7. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P1730.

Did the result indicate a fail?

YES: Go to step 8.

NO: Intermittent failure, the system is OK at this time. If the tester indicates NOT
COMPLETE, return to step 5 and recheck.

8. Clear the DTC with the HDS.

9. Select SHIFT SOL TEST in MISC. TEST MENU, then carry out A/T SHIFT SOL A test in SHIFT SOL

TEST MENU with the HDS.

Is a clicking sound heard?

YES: Go to step 10.

NO: Replace shift solenoid valve A (see SHIFT SOLENOID VALVE
REPLACEMENT
), then go to step 15 .

10. Select SHIFT SOL TEST in MISC. TEST MENU, then carry out A/T SHIFT SOL B test in SHIFT SOL

TEST MENU with the HDS.

Is a clicking sound heard?

YES: Go to step 11.

NO: Replace shift solenoid valve B (see SHIFT SOLENOID VALVE
REPLACEMENT
), then go to step 15 .

11. Select SHIFT SOL TEST in MISC. TEST MENU, then carry out A/T SHIFT SOL D test in SHIFT SOL

TEST MENU with the HDS.

Is a clicking sound heard?

YES: Go to step 12.

NO: Replace shift solenoid valve D (see SHIFT SOLENOID VALVE
