Unfortunately you reset the PCM so if there were any trouble codes, you deleted them. You should always check first before going this route. More than likely, you have a loose connection somewhere or bad ground causing the issue since the information center reads exactly what the PCM is telling it. A bad battery can also wreak havoc with the system but there are usually other signs the battery is going bad. Mechanically speaking, the DCT has an excellent service record with very few instances of mechanical failure.
