Great conversation. I've been casually researching this topic for the past few years. I found good info on the install and such, but nothing on "why" people did the install the way they did. Good to see some "why" happening here.
I don't get why these trannys get so hot. In my old Bronco, I used to beat on it for 10-14 hours at a time (WAY more abuse than the GP has ever seen), and I never had heat issues at all. I am starting to believe that the radiator in these cars is insufficient.
