Tod74, If you do not feel that heat is an issue for you, company's do make tranny blankets out of kevlar or similar that will give you protection from explosions in the trans area. The down side is that if you have a leak it will get unnoticed until it drips and does trap a lot of heat in your trans case and oil, but some programs in bracket racing that run 1/8th mile like I think you have been doing? will be less affected by the heat issues some cars can have even without a blanket. I personally, used to put a large blanket in the car over the trans just in case....... .040 aluminum is like holding a piece of newspaper over a bomb if you know what I mean and I think you do.
Something is better than nothing.
