DTC Troubleshooting
DTC P0732: Problem in 2nd Clutch and 2nd Clutch Hydraulic CircuitNOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review General Troubleshooting Information.
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, then go to step 13.
No - Replace the ATF, then go to step 4.
4. Measure the line pressure. Is the line pressure within the service limits?
Yes - Go to step 5.
No - Repair the ATF pump and the regulator valve, or replace the transmission, then go to step 12.
5. Measure the 2nd clutch pressure.
Is the 2nd clutch pressure within the service limits?
Yes - Go to step 6.
No - Shift valves A, B, and C are stuck. Repair these valves and the related hydraulic circuit, or replace the transmission, then go to step 12.
6. Test stall speed in 2.
Does the stall speed test within the service limits?
Yes - Go to step 7.
No - Shift valve C is stuck. Repair shift valve C and hydraulic circuit, or replace the transmission, then go to step 12.
7. Clear the DTC with the HDS.
8. Test-drive the vehicle. Start off in D, and run the vehicle in 2nd gear at speeds over 7 mph (12 km/h) for at least 12 seconds, then slow down to a stop.
9. Turn the ignition switch to LOCK (0), and repeat step 8, then go to step 10.
10. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
Is DTC P0732 indicated?
Yes - Repair the 2nd clutch, or replace the transmission, then go to step 12.
No - Go to step 11.
11. Monitor the OBD status for P0732 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate PASSED?
Yes - Intermittent failure, the system is OK at this time. If any other DTCs were indicated in step 10, go to the indicated DTC's troubleshooting.
No - Check for poor connections and loose terminals at the input shaft (mainshaft) speed sensor, the output shaft (countershaft) speed sensor, and the PCM, then recheck. If the HDS indicates NOT COMPLETED, return to step 8 and recheck.
12. Clear the DTC with the HDS.
13. Test-drive the vehicle. Start off in D, and run the vehicle in 2nd gear at speeds over 7 mph (12 km/h) for at least 12 seconds, then slow down to a stop.
14. Turn the ignition switch to LOCK (0), and repeat step 13, then go to step 15.
15. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.
Is DTC P0732 indicated?
Yes - Check for poor connections and loose terminals at the input shaft (mainshaft) speed sensor, the output shaft (countershaft) speed sensor, and the PCM, then go to step 1.
No - Go to step 16.
16. Monitor the OBD status for P0732 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.
Does the HDS indicate PASSED?
Yes - Troubleshooting is complete. If any other DTCs were indicated on step 15, go to the indicated DTC's troubleshooting.
No - Check for poor connections and loose terminals at the input shaft (mainshaft) speed sensor, the output shaft (countershaft) speed sensor, and the PCM, then go to step 4. If the HDS indicates NOT COMPLETED, return to step 13 and recheck.
