Did you check the electronic connection plug on the TIP. It plugs in under the car so you can remove the TIP. You may have moisture or water there...use a top quality electrical contact cleaner if necessary. The ECU under the drivers set needs to be checked by a Porcshe dealer. If it's bad the cost is around $1500. Now, if your TIP is bad, look for a used one at a Porsche dismantler. Mike, my fluid was the same color...you should have drained the fluid very well and it should have only taken 6-7 liters of fluid...ONLY that since you cannot drained the converter or fluid from the front oil cooler.
