T-45 getting hot.........

Pretty normal actually, especially with warmer weather coming. Mustangs tend to run a little hot in the trans area since th head from the H-pipe tends to collect there. I notice it on my Fox Mustang and my GT. If i cruise around on a warm day with shorts on and the windows down, my right leg will start to feel warm after a while.

If it will make you feel better, check the fluid level in your trans. Just unscrew the top fill plug and check to see if the level is up to the plug. If it is, you are good to go.
