Your coolant level sensor is either broken inside of the expansion tank, the connection is loose or you have a broken wire near the sensor. All of these are very common on your car. As for the transmission, you can change the chip but you need someone to write you a less aggressive map. Most chips available aftermarket hang 3rd gear longer for "performance" reasons; not what you're looking for.
