Disconnecting the battery clears the codes. Just because they are gone doesn't mean everything is fixed. Also, you might need a better source for code definitions. A Code 11 is telling you transaxle codes are present. There is no code 16.

Here is a link to help you diagnose your quad driver fault.

Have you replaced your Engine Coolant Temperature Sensor? Your car has a resin tipped sensor that will crack from the coolant sending false data to the PCM. This sensor is VITAL to many systems of the car including: air/fuel mixture, idle speed, shift points, TC lock up times, fan control, etc. The new ones are brass tipped and will last the life of the car. If this sensor goes bad it rarely sets on its own SES light. This would be my first step if I was you. Your car car two sensors, you need to replace the one with the 2-wire connector.
