DTC Troubleshooting (cont’d)
26. Monitor the OBD STATUS for P0713 in the DTCs
MENU with the HDS.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs were indicated in step 25,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals between the ATF
temperaturesensorandthePCM,thengotostep1.
If the HDS indicates NOT COMPLETED, go to step
24.
27. Reconnect all connectors.
28. Update the PCM if it does not have the latest software (see page 11-227), or substitute a known-
good PCM (see page 11-7).
29. Start the engine with the shift lever in P, and wait for at least 20 seconds.
30. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals between the ATF temperature sensor and
the PCM. If the PCM was updated, substitute a
known-good PCM (see page 11-7), then go to step
29. If the PCM was substituted, go to step 1.
Go to step 31. 31. Monitor the OBD STATUS for P0713 in the DTCs
MENU with the HDS.
If the PCM was updated, troubleshooting is
complete. If the PCM was substituted, replace the
original PCM (see page 11-228). If any other
Temporary DTCs or DTCs were indicated in step 30,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, check for poor
connections or loose terminals between the ATF
temperature sensor and the PCM. If the PCM was
updated, substitute a known-good PCM (see page

NOTE:
 Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-3).
 This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the
transmission.
1. Check for proper input shaft (mainshaft) speed sensor installation (see page 14-227).
2. Turn the ignition switch to ON (II).
3. Clear the DTC with the HDS.
4. Block the rear wheels and raise the front of the vehicle, make sure it is securely supported, and
allow the front wheels to rotate freely, or raise the
vehicle on a lift.
5. Start the engine, disable the VSA by pressing the VSA OFF switch (if equipped), run the vehicle with
the shift lever in D at speeds over 20 km/h (12 mph)
for at least 10 seconds. Slow down and stop the
wheels.
6. Monitor the OBD STATUS for P0716 or P0717 in the DTCs MENU with the HDS.
Go to step 7.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals between the
input shaft (mainshaft) speed sensor and the PCM.
If the HDS indicates NOT COMPLETED, go to step 5. 7. Turn the ignition switch to LOCK (0).
8. Jump the SCS line with the HDS.
9. Disconnect PCM connector C (44P).
10. Check for continuity between PCM connector terminal C40 and body ground, and between PCM
connector terminal C44 and body ground.
Go to step 11.
Repair open in the wires between PCM
connector terminals C40, C44, and body ground
(G101) (see page 22-16), or repair poor body
ground (G 101), then go to step 26.
