I always warm up with R/s and have no problems SO FAR... I just passed 2000 miles.. I also have an 08 and asked for the ecu update + tranny fluid and they said 08s have no updates so far. They are however VERY willing to allow me to test drive the car with the manager to show him my transmission symptoms when they do arise so that we can take care of it. I HOPE that our cars came with the new transmission fluid or I am going to be very sad
