Could it be done ? :) ive been throwing this idea around for awile now im thinking if a just get a BIG Transmission cooler i could do it but i dont know a transbrake could just destroy my transmission :-/ anyone ever try this? or have any experiences with transbrakes

I have a transbrake on my 1955 Chevy that I drive on the street all of the time (it also has a manual shiftbody). Maybe you are confused about the operation of a transbrake because if you don't engage it it makes no difference in the functioning of the trans. If you have a strong engine a hard launch on the street with a transbrake can be very intimidating to anyone who sees it. Have fun!
