transmission cooler used as oil cooler?

I bought a 90 Maxima radiator to put into my 240 and it has a built in transmission cooler. I was wondering how efficient it would be to use the transmission cooler as an oil cooler and if the 11-60 psi will blow out the transmission cooler?

if you are going to use an oil cooler, grab one from a saab in a junkyard. way more efficient than the built-in rad ones.
