NOTE: Record all freeze data and review General Troubleshooting Information before you troubleshoot.

1. Warm up the engine to normal operating temperature (the radiator fan comes on).
2. Make sure that the transmission is filled to the proper level, and check for fluid leaks.
3. Drain the ATF through a strainer. Inspect the strainer for metal debris or excessive clutch material.
Does the strainer contain metal debris or excessive clutch material?
YES - Replace the transmission.
NO - Replace the ATF then go to step 4.

4. Clear the DTC with the HDS
5. Test-drive the vehicle in the D position through 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 through all five gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
7. Monitor the OBD status for P1733 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate a failed?
YES - Go to step B.
NO - intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETED, return to step 5 and recheck.

8. Clear the DTC with the HDS.
9. Choose Shift Solenoid D in Miscellaneous Test Menu, and check that the shift solenoid valve D operates with the HDS.
Is a clicking sound heard?
YES - Go to step 10.
NO - Replace shift solenoid valve D, then go to step 15.

10. Choose Clutch Pressure Control (Linear) Solenoid C in Miscellaneous Test Menu, and test the A/T clutch pressure control solenoid valve C with the HDS.
Is the system OK?
YES - Go to step 11.
NO - Follow the instructions indicated on the HDS by the tester result, but if the tester has not determined the cause of the failure, go to step 14. If any part was replaced, go to step 15.

11. Test-drive the vehicle in the D position through all five gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
12. Retest-drive the vehicle in the D position through all five gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
13. Monitor the OBD status for P1733 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate a failed?
YES - Repair hydraulic system related with shift valve D, or replace the transmission, then go to step 15.
NO - intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETED, return to step 11 and recheck.

14. Inspect A/T clutch pressure control solenoid valve C.
Does the A/T clutch pressure control solenoid valve C work properly?
YES - Repair hydraulic system related with shift valve D, or replace the transmission, then go to step 15.
NO - Replace A/T clutch pressure control solenoid valve C, then go to step 15.

15. Clear the DTC with the HDS.
16. Test-drive the vehicle in the D position through all five gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
17. Retest-drive the vehicle in the D position through all five gears at speeds over 12 mph (20 km/h) for more than 20 seconds, then slow down to a stop.
18. Monitor the OBD status for P1733 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate a passed?
YES - Troubleshooting is completed.
NO - Return to step 8 and recheck.
