It get is hot due to lack of air flow through the transmission cooler. If you are concerned about it you could install an after market cooler with its own fan. I have one that I am installing in my truck for the same reason. I am installing a Derale Atomic Cool. Putting the truck in neutral will reduce the temperature climb.
Adding a deep transmission pan will also extend your transmission life. I like the Mag-Hytec ones.
