why you can't, a/c condenser

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.

AC condensors make terrific coolers!! I have done this for years with no problems.
The passages are larger than the cooler lines,so there is lots of flow,
they have MUCH more cooling surface area than even the largest aftermarket cooler,
and the trans fluid pressure is much lower than Freon, so you will not burst the condensor.
