Not sure, but you may need a more sophisticated scanner that will also report special codes that for instance the transmission module communicates to the powertrain control module (PCM- the main computer on the vehicle, but nowadays there are also computers on several other systems, like the transmission and the chassis electrical system, and the ABS system. They all communicate with the PCM. I thought all codes were available from the PCM, but maybe not in your case. Anyway, if you have a friend with a more high-end scanner, try scanning it again. Or try at Autozone, and see what their free scan says.
