2002 Honda Accord Shift Malfunctioning

Hi rvirdi,

DTC P0780/45: MECHANICAL FAULT IN HYDRAULIC SYSTEM

NOTE:
DO NOT perform this DTC test until all other DTCs have been repaired first.

1. Using scan tool, retrieve freeze data. Clear DTCs and road test vehicle under same conditions freeze 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 P0780/45. If no other DTCs are present, go to next step.

3. Replace lock-up control solenoid valve/shift control solenoid valve "A" assembly and A/T clutch pressure control solenoid valve "A"/"B"assembly.

4. Clear DTCs. Road test vehicle for several minutes in "D4" position. Ensure transaxle shifts into all gears. Recheck DTCs. If DTC P0780/45 returns, replace transaxle. If DTC P0780/45 does not return, system is okay.
