All claims submitted that have incomplete, illegible, or missing documentation are subject to debit. SERVICE PROCEDURE: 1. Attach a GDS and select DTC Analysis and A/T menu. Record the DTC and description. Delete the DTC. 2. From the GDS home screen, select Data Analysis and A/T menu and the parameters shown below. If the parameters show: • Continuous and changing output while driving, the wiring currently has no open/short circuits. Go to Step 4. • No continuous and changing output, go to Step 3. TSB #: 23-AT-007G Page 2 of 7 3. Visually check the wiring harness between the TCU and transmission for a damaged wire or connector. Check for an open/short circuit. • If so, repair or replace the control harness and drive the vehicle to confirm the repair. • If no damage is found, go to Step 4. 4. Record the audio preset stations and disconnect the negative battery terminal. 5. Lift the vehicle on a hoist. Locate the harness connector on the passenger side of the transmission. Press the tab in the center of the latch and push the latch upward. Push the connector up to disconnect the connector from the valve body. If additional clearance is needed to access the connector, place a support under the rear transmission support, loosen the bolts about ½ inch and lower the support about ½ inch. 6. Use an 8mm or 5/16” hex wrench and remove the drain plug and drain the ATF. Reinstall the drain plug. Torque: 17~18 lb.ft (2.3~2.5 kgf.m, 22~24 N.m) Remove bolts that secure oil pan and remove the oil pan. 7. Remove 10 bolts that secure the valve body to the case and remove the valve body. Note the location of the 3 black bolts (shown with black arrows). If the valve body is stuck in the transmission, insert a screwdriver between the valve body and case and carefully pull the valve body out of the transmission. TSB #: 23-AT-007G Page 3 of 7 8. Remove 9 bolts and remove the E-module. Install a new E-module and torque the bolts to specification. Torque: 7~9 lb.ft (1.0~1.2 kgf.m, 10~12 N.m) NOTE: Install the short bolt in the location shown in the circle. 9. FOR SHIFT-BY-CABLE (SBC): Confirm that 5 O-rings are seated in the case. FOR SHIFT-BY-WIRE (SBW): Confirm that 4 O-rings are seated in the case. 10. Place the valve body on a transmission jack. Rotate the park switch lever in the direction of the arrow. Carefully raise the valve body and insert the manual valve into the lever. Install the valve body fully into the transmission case. NOTICE Confirm the pin on the park switch lever faces outward from the valve body. TSB #: 23-AT-007G Page 4 of 7 11. Install 3 black bolts in the locations shown (black arrows). Install 7 brass bolts in the location shown (red arrows). Torque the bolts to specification. Torque: 7~9 lb.ft (1.0~1.2 kgf.m, 10~12 N.m) 12. Reconnect the harness connector. Use a 90° pick or similar tool to pull the connector down into position on the valve body. Pull the latch down until it clicks into the tab. 13. Confirm the O-ring is installed at the location shown. Reinstall the valve body cover and torque to specification. Torque: 10~12 lb.ft (1.4~1.6 kgf.m, 14~16 N.m) TSB #: 23-AT-007G Page 5 of 7 14. With the engine off, lift the vehicle on a hoist. Use an 8mm or 5/16” hex wrench and remove the fill plug and washer. Torque: 25~32 lb.ft (3.4~4.4 kgf.m, 33~43 N.m) 15. Remove the overflow plug. Use a fluid pump or suction gun to add SPH-IV-RR ATF through the fill plug until ATF flows from the overflow plug. Reinstall the fill plug, washer and overflow plug. . NOTICE Use only SPH-IV-RR ATF, P/N 00232-19052. 16. Lower the vehicle. Reconnect the negative battery terminal. Reset the audio preset stations. 17. Attach a GDS and select vehicle, Data Analysis, A/T menu and Oil Temperature Sensor. Move the shift lever from P-R-D and back to P. Drive the vehicle until the ATF is at the low end of the range of 122~140°F (50~60°C). TSB #: 23-AT-007G Page 6 of 7 18. Start the engine, shift to Neutral and raise the vehicle on a hoist. Remove the fill plug, washer and overflow plug. Add SPH-IV-RR ATF through the fill plug until the ATF flows out the overflow. Reinstall the overflow plug. Torque: 17~18 lb-ft (2.3~2.5 kgf.m, 22~24 N.m) Reinstall the fill plug and washer. Torque: 25~32 lb.ft (3.4~4.4 kgf.m, 33~43 N.m) ATF TEMPERATURE = 122~140°F (50~60°C) SHIFT LEVER IN “P” AND ENGINE RUNNING 19. FOR SBW PARK POSITION SWITCH: If the shift cable was moved to add ATF: Install the SST (09480-D2100) or 5mm bolt in the alignment hole of the park position switch. Loosen the adjustment bolt shown. Slide the adjustment bracket rearward to remove the slack in the park cable. Tighten the bolt to specification. Torque: 7~8 lb-ft (0.9~1.0 kgf.m, 9~10 N.m) SST Bolt 20. Test drive the vehicle for two driving cycles (two key-on to key-off driving cycles, including 1-23-4-5-6-7-8 upshifts and 8-7-6-5-4-3-2-1 downshifts). If the DTC returns, perform the following repairs: DTC P071100 P071200 P071300 P071700 P072100 P072200 DTC REPAIR PROCEDURE Replace the control wiring harness between the TCU and transmission. ➢ If the DTC does not occur again, return the vehicle to the customer. ➢ If the DTC returns again, replace the TCU. 21. Drive the vehicle to confirm the proper operation of the transmission. TSB #: 23-AT-007G Page 7 of 7
