Talked to Gavin today. He said it's because of the tune and to just not push the car as hard until the new tune comes out. He said there should be no issues with the trans it just failed and made me limp to protect it which is what I figured. He also said to have the dealership file a warranty claim to roush because they would like to keep track of all the cars having issues. So in case anyone else has this issue call roush and report it or your dealer and to reset the failure all it requires is to turn the car off and on again.
