I have seen some people do swap out the trans fluid to something else and it might help make shifting a bit smoother. My 1-2 and sometimes 2-3 shifting can feel a bit more notchy and crunchy than I like until it gets temperature into the fluid. I have read that a different fluid can help with that. I would definitely do the diff fluid with the oil at 500, and if you want, do so again at 1500, then I follow the oil life indicator. People always say this is a waste but it gave me more peace of mind. I found the magnetic drain plug had material on it both times. Also, make sure your coolant levels are correct. There are two tanks. A lot of people had the expansion tank below where it should be from the factory, myself included. Main tank filled all the way up and the expansion tank to the cold line. Procedure to fill is in the owners manual.
