Here are the diagnostic procedures.
DTC P0730/41: SHIFT CONTROL SYSTEM
DO NOT perform this DTC test until all other DTCs have been repaired first.
1. Using scan tool, retrieve A/T freeze data. Clear fault codes and road test vehicle under same conditions freeze data was recorded. If fault code returns, go to next step. If fault code does not return, problem is intermittent, check transaxle and PCM connections.
2. Road test vehicle at over 12 MPH for more than 30 seconds in 2nd, 3rd and 4th gear. Using scan tool, check for any other DTCs. If any other DTCs are present, repair those DTCs first, then recheck for DTC P0730/41. If no other DTCs are present, go to next step.
3. Test clutch pressure. If clutch pressure is within specification, go to next step. If clutch pressure is not within specification, repair hydraulic system as necessary.
4. Replace lock-up control solenoid valve/shift control solenoid valve "A" assembly and shift control solenoid valves "B" and "C". Turn ignition off and clear codes.
Road test vehicle at over 12 MPH for more than 30 seconds in 2nd, 3rd and 4th gear. Recheck DTCs. If P0730/41 returns, replace transaxle. If P0730/41 does not return, system is okay.
