By all means take it back and show them reciept from previous repair attempt.
Is is possible the trans. Temp sensor is bad or connection to it, especially if the cooling temp gauge is not showing you are overheating. This also makes sense that after you went to car wash, the trans temp light is on again (assuming that is what the scan will show).
If problem reappears after second repair, complain directly to service manager and if that doesn't work complain to Dodge.
I would also consider taking to a different Dodge dealer, I am assuming the car is still under warranty.
Keep you reciepts as evidence for future problems.
