Best Location For Tranny Cooler ??

[gsrsol84mm]

I have my B&M tranny Cooler and external filter ready to install, but the question is where ? I have asked a few people and each one gives a different answer. Some say up front, some say on the drivers side, some say horizontal with a fan, others say cut a hole in the plastic guard to let air flow.
Some say tranny, then external filter then radiator then cooler then tranny. Others say NO, tranny, external filter, radiator, cooler then tranny.
Please help, it's the last thing I have to do to finish my car. Tranny is a rebuild by cottman from the previous owner with about 250 miles on it.
I have tried the search but just get more confused. A picture would really help.
