DTC LIST & PARTS INFORMATION:
WARRANTY INFORMATION - Solenoid replacement (BH & BK):
WARRANTY INFORMATION - Pressure switch replacement (BH, BK & VI):
SERVICE PROCEDURE:
1. Using a GDS, check for DTC in the "Automatic Transaxle" menu. Record the DTC and description. Delete the DTC.
2. From the GDS, select the following menus:
^ Vehicle and A/T menu
^ "Actuation Test"
^ Press the "Start" button and look for a "Success" indication and listen for a solenoid operation noise. If necessary, use Chassis Ears or a stethoscope.
3. If the test results show:
^ "Success" - The GDS requested the TCM to activate the solenoids. Use a stethoscope or Chassis Ears to confirm the solenoid operation. If the solenoids are audible, the harness currently has no open/short circuit. Go to Step 5.
^ "Failure" - The GDS did not request the TCM to activate the solenoids. Go to Step 4.
4. Visually check the wiring harness between the PCM and transmission for a damaged wire or connector. Check for a open/short circuit.
^ If so, repair or replace the ECM control harness and drive the vehicle to confirm the repair.
^ If no damage, go to Step 6.
5. Disconnect the negative battery terminal.
6. Lift the vehicle on a hoist.
Press the tab in the center of the latch and push the latch upward.
Push the connector up to disconnect the connector.
7. Use an 8mm or 5/16 hex socket and remove the drain plug and drain the ATF. Reinstall the drain plug.
Torque: 17~19 lb.ft (2.4~2.6 kgf.m)
Remove the 14 bolts that secure the oil pan and remove the pan.
8. Remove the 10 bolts that secure the valve body to the case and remove the valve body.
Note the location of the 3 black long bolts.
9. Remove 8 bolts and remove the E-module. Install a new E-module after solenoid replacement.
Torque: 6~7 lb.ft (0.9~1.0 kgf.m)
10. P0841 only:
If P0841 was recorded in Step 1, disconnect the connector and replace the pressure switch, P/N 46306-4E000. Reconnect the connector.
Torque: 3~4 lb.ft (0.4~0.5 kgf.m)
If P0841 was not recorded, go to Step 11.
11. Refer to the solenoid DTC recorded in Step 1 and replace the related solenoid. Refer to the PNC in the parts catalog.
12. Remove two bolts and remove the solenoid support.
13. Use a magnet to remove the pin and remove the related solenoid.
Install a new solenoid.
Install the pin and the solenoid support.
14. Use a 5mm hex socket to remove 4 bolts that secure the support to the valve body and remove the support.
Remove the related solenoid.
Install a new solenoid.
Install the support.
15. Install a new E-module and torque to specification (See Step 9).
Torque: 6~7 lb.ft (0.9~1.0 kgf.m)
ASSEMBLY
16. Confirm that 5 0-rings are seated in the case.
17. Carefully align the manual valve to the shift lever and install the new valve body.
18. Install 10 bolts and torque to specification.
Install the 3 long black bolts in the correct location.
Torque: 7.2~8.7 lb.ft (1.0~1.2 kgf.m)
19. Reconnect the harness connector and pull the latch down until it clicks (See Step 6).
20. Install the oil pan and torque the bolts to specification.
Torque: 10~12 lb.ft (1.4~1.6 kgf.m)
21. Reconnect the negative battery terminal.
22. Use an 8mm or 5/16" hex socket and remove the fill plug and washer.
Shift into Park and lift the vehicle on a hoist.
Use a fluid pump or suction gun to add approximately 4 quarts of SPH-IV-RR ATF through the fill plug.
NOTE
Use only SPH-IV-RR ATF, P/N 00232-19052.
23. Remove the overflow plug. Start the engine.
Add approximately 4~5 additional quarts of SPH-IV-RR ATF through the fill plug until the ATF flows out in a thin steady stream.
Reinstall the fill plug and washer.
Torque: 27~33 lb.ft (3.7~4.6 kgf.m)
Reinstall the overflow plug.
Torque: 16~18 lb-ft (2.3~2.5 kgf.m)
24. Attach a GDS and select vehicle, A/T menu, Current Data and Oil Temperature Sensor.
25. Drive the vehicle until the ATF is at the low end of the range of 122~140°F (5O~6O° C).
26. Move the shift lever to "P" and leave the engine idling. Raise the vehicle on a hoist.
Remove the overflow plug. The ATF level is correct when the ATF flows out in a steady, thin stream.
27. Attach a GDS and reset the adaptive learning. Select VIN, A/T menu, "Option Treatment and "Resetting Auto T/A values. Follow the screen prompts.
Follow TSB 12-AT-017 to relearn the TCM. Erase any DTC.
28. Drive the vehicle to confirm the proper operation of the transmission.
