2000 Honda Accord Code P0730 and P1750

Hi art wright,

Here are the description of the problems.

DTC P0730/41: SHIFT CONTROL SYSTEM
NOTE:
Do not perform this DTC test until all other DTCs have been repaired first.

1. Using scan tool, retrieve freeze frame data. Clear DTCs and road test vehicle under same conditions freeze frame data was recorded. If DTC returns, go to next step. If DTC does not return, problem is intermittent. Check transaxle and PCM connections.

2. Road test vehicle at greater than 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, and 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 DTCs. Road test vehicle at greater than 12 MPH for more than 30 seconds in 2nd, 3rd and 4th gear. Recheck DTCs. If DTC P0730/41 returns, replace transaxle. If DTC P0730/41 does not return, system is okay.

DTC P1750/46: MECHANICAL FAULT IN HYDRAULIC SYSTEM

1. Using scan tool, retrieve freeze frame data. Clear DTC and road test vehicle under same conditions freeze frame data was recorded. If DTC returns, go to next step. If DTC does not return, problem is intermittent, check transaxle and PCM connections.

2. Using scan tool, check for any other DTCs. If any other DTCs are present, repair those DTCs first, then recheck for DTC P1750/46. If no other DTCs are present, go to next step.

3. Replace A/T clutch pressure control solenoid valve "A"/"B"assembly.

4. Clear DTC. Road test for several minutes in "D4", ensure transaxle shifts into all gears. Recheck DTCs. If P1750/46 returns, replace transaxle. If DTC does not return, system is okay.
