a/c condenser to transmission cooler

why can't you change a a/c condenser to a transmission cooler. truck is a 70 1/2ton, with the th350 transmission with all the a/c missing. removed the condenser, but was thinking why can't i make that thing cool the transmission fluid. all the a/c oil is out of it. no promblem pluging old transmission lines in radiator and move them to a/c condenser. can anyone give me a reason why can't? the olny problem i see is the transmission can't pump the fluid. i can put a electric pump inline to push the fluid through the condenser.

talk to me

A trans cooler and auxillary fan costs about $120.00, while a transmission starts at $2000.00 That's why

why what? i'm not buying a transmission, i'm cool ing it with a biger cooler.

Who needs a fan? as long as the truck is going forward it's cooling.
