Re: Ultramatic Transmission External Trans. Fluid Cooler - 1956

my 55 has a round tube external cooler in place of the original cooler.

i have seen flat tube units before, but i dont know where. try looking for heavy duty units for large pickups. my 1993 dodge with the chrysler a518 drove for 2.5 hours on the highway and the fluid could still be held between the fingertips.

you really cant over cool automatics. the cooler the better.
