When the shop rebuilt my tranny they put on a second cooler. its not as big as the tru-cool max but i think its like the one that is one step smaller. so the lines enter the radiator, exit then go through the one they added and then back to the tranny. my truck did not have anything but the radiator cooler (pretty strange if you ask me for a f350 made to haul...)
so the one i got is attached behind the intercooler pretty low (about where the bumper is) so i was thinking that being attached to the intercooler it will pick up lots of heat and being behind the bumper area there is not very much air hitting it.... so i think a tru-cool max is in my future...
raul - that one you sell with the fan, does that come with hose and mounting parts? is it the same one that is on your truck now? it looked like a pretty sweet setup when i saw it last visit to kalifornia.
