Usually, with A604 transmission, changing both input and output sensor solves the problem. If it doesn't, then you need to check the transmission control module, before you replace it.

P0700 Transmission Control System Malfunction
P0725 Engine Speed input Circuit Malfunction

You don't have to go back to the dealer. Autozone and CSK/O'Reilly can reset the computer for you. You can also unplug the negative battery terminal for more than 30 minutes to reset it yourself, but then you have to reset your clock and radio stations, and stuff, and the computer has to re-learn everything else. Based on the codes (P0700), I believe you have to replace your transmission control module. That was what I had to do with mine several years back.
