DTC P1743: Problem in Shift Control System; Shift Valve E Stuck OFF

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 have 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 for several minutes in the D position through all five gears. Slow down and stop the wheels.
6. Retest-drive the vehicle for several minutes in the D position through all five gears. Slow down and stop the wheels.
7. Monitor the OBD status for P1743 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate FAILED?
YES - Repair shift valve E in the main valve body, replace the main valve body, or replace the transmission.
NO - intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETED, return to step 4 and recheck.
