Hey guys just picked up a Clean 97 F250 With a smoked transmission so I had the tranny built locally and decided to upgrade the cooler lines to the super duty 3/8 lines and install a 6.0 trans cooler. In order to install the Super Duty cooler lines you have to change the fittings on the trans to accept the bigger lines which I had my trans guy do during the rebuild. The Super Duty lines require just a slight bend by the starter but they really go on pretty easy. The stock line mount at the front of the engine also works with the bigger lines.
Here is the stock Cooler setup
Here is the stock external cooler vers the 6.0 cooler
I decided to mount it out front but there is a tab on the back side of the header panel I had to cut off to get it in there.
Couple pics of the tab
And tab is now gone
Here is my final mounting position of the cooler
I used 3/8 compression Fittings on the cooler lines from the trans that then adapted to a female NPT pipe thread. I got Fittings that went from male NPT pipe to a push-lock and then used 1/2 push-lock hose up to the cooler. I also did away with the internal radiator trans cooler. I hate not knowing if my radiator is about to leak into the trans cooler and destroy my new transmission. I have this same cooler on my E99 which didn't even come with the internal radiator cooler from the factory. This cooler by itself on my 99 keeps my trans at 160 or less no matter what I tow or how hard I push it.
How I routed/protected the lines through the radiator support. I slide 3/4 inch heater hose over the push-lock hose to prevent cuts and chafing where it goes through the radiator support.
Here is how I secured the lines up front
And just a couple pics of the rest of the project
Decided now was a good time to cut the stupid flat down pipe off and install a real exhaust
Hope this helps someone out and let me know if there are any questions
