Automatic Transmission Cooler Lines

I am not very educated on the subject but i looked at the manufacture specs on my braided steel line and it is rated for 2500 psi and fluid temps from -65 to 400 degrees. they also show hydraulic fluid being safe to run thru the lines. here is my set up. i run duel coolers with braided stainless lines and AN fittings. i have about 65 hard miles on the set up and not a single leak.
