Temporary DTCs or DTCs were indicated in step 15,
go to the indicated DTC’s troubleshooting.
If the HDS indicates FAILED, go to step 8. If
the HDS indicates NOT COMPLETED, go to step 14.  Shift Solenoid Valves B or C Stuck ON
 Shift Valves B or C Stuck
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). 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 (see step 3 on page 14-232) through a strainer. Inspect the strainer for metal debris or
excessive clutch material.
Replace the transmission, then go to step 13.
Replace the ATF (see page 14-232), then go to
step 4.
4. Turn the ignition switch to ON (II).
5. Clear the DTC with the HDS.
6. Test-drive the vehicle with the shift lever in D, and let the transmission shift through all five gears.
7. Monitor the OBD STATUS for P1732 in the DTCs MENU with the HDS.
Go to step 8.
If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. If the HDS
indicates NOT COMPLETED, go to step 6.
8. Clear the DTC with the HDS.Problem in Shift Control System:

1. Make sure the transmission fluid is filled to the
proper level (see page 14-231).
2. Apply the parking brake, and block all four wheels.
3. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
4. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).
5. Make sure the A/C switch is OFF.
6. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
7. Shift to D while pressing the brake pedal firmly, then fully press the accelerator pedal for
6 to 8 seconds, and note the engine speed. Do not
move the shift lever or remove your foot off the
brake pedal while raising the engine speed.
8. Allow 2 minutes for cooling, then repeat the test in SandR.
NOTE: Do not test the stall speed for more than 10 seconds at a time.
 The stall speed tests should be used for diagnostic purposes only.
 Stall speed test results should be the same with the shift lever in D, S, and R.
 Do not test the stall speed with the A/T oil pressure gauges installed. 9. If the stall speeds are out of the service limit, the
problems and probable causes are listed in the
table.

pressure inspection port (A). Do not allow dust or
other foreign particles to enter the ports while
connecting the gauges.
8. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
9. Measure the line pressure at the line pressure inspection port with the shift lever in P or N while
