1.

Check the ATF temperature with the HDS in the A/T data list. Does the ATF temperature exceed an ambient-air temperature? YES - Record the ATF temperature. Leave the engine off for more than 30 minutes, and go to 2. NO - Record the ATF temperature. Test the stall speed RPM three times. Go to 2 after stall speed testing.

2.	Check the ATF temperature with the HDS. Does the ATF temperature change? YES - Leave the engine off for more than 30 minutes, and go to 3. NO - Replace the ATF temperature sensor, then go to 5.

3.	Check the ECT SENSOR with the HDS. Is the ECT SENSOR equal to the ambient-air temperature? YES - Go to 4. NO - Leave the engine off until the ECT sensor equals the ambient-air temperature, then go to 4.

4.	Check the ATF temperature with the HDS. Is the ATF temperature almost equal to the ECT SENSOR? YES - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ATF temperature sensor and the PCM.n NO - Replace ATF temperature sensor, then go to 5.

5.	Clear the DTC with the HDS.

6.	Test-drive the vehicle for several minutes in the D position through all five gears.

7.	Monitor the OBD status for P0711 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail. Does the result indicate PASSED? YES - Troubleshooting is complete.n NO - Return to 1 and recheck.
