7.3 trans cooler upgrade

I have an early 99 7.3 and am wanting to upgrade the trans cooler to a 6.0 trans cooler. First question is do the 6.0 trans coolers bolt right in to the old mounting spots or do I have to get different mounts, and do the fluid lines mout up the same. Next question is does anyone have the full procedure of how to swap these out? Sorry for all the questions I really want to do this upgrade but dont know where to start.

DIRECT bolt up.
It's very straight forward.
The lines on a 7.3 are 3/8" IIRC and the the 6.0 is a 1/2". The lines are in diff spots too but just get some adapters and different hose and you're good.

i followed this write up. i bought the 3/8 to 1/2 fittings off line. you will also need 2-3 qts of tranny fluid, 4 ft of 1/2 line, 4 hose clamps.

That's a great write up. That covers it.

I wished I had done the bumper removal part. It would have been a bit easier.

The cooler on my truck does not look like that....WTF? It seems to be mounted in front of the condenser by bolts going through it.

Has anyone had this issue?

That's your power steering cooler.

IIRC early 99s didn't have a separate trans cooler, it's built into the bottom of the radiator. I could be completely wrong though.
