Honda civic 2004 automatic transmission issue

[fycel_khan]

Please help me. My car is having some issues. It’s a 2004 Honda Civic Prosmatec, automatic transmission. The previous owner had installed a D2 automatic transmission, but the card installed is for D3 (Japanese version). Because of this, the D3 error showing on scanning

After the car heats up—around 13 km of driving—it shifts from 1st to 2nd gear with a jerk.

Please help me understand what should be done. Also, if possible, guide me to a reliable gear mechanic who can fix this issue by either repairing or replacing the gear and its card, as this car is used for daily driving.

the problem could be simply because of the card or maybe a pressure switch.

You should initially scan your car and then look for a mechanic. Civic prosmatecs can be a pain in the back often its hit and try.

Also you need to get to a honest mechanic, If you are near DHA, I can refer you several places in DHA Phase 2, nera KElectric office.
