I bought a transmission cooler.and when looking and planning the mounting, I noticed the return cooler line from the radiator, goes up into what looks like, between the A/C coil and the radiator. Is there another cooler up there? It is pouring the rain here right now or I would be looking. I have looked at my build sheet from parts guy Ed. and I can't find any mention of a cooler.
I have a very late 2003 7.3 Thanks for any ideas. Jim

 

If your truck is a automatic it has a trans cooler between the a/c coil and the intercooler, pull back the rubber thing under the hood and you can see it.

 

Thanks jwhitetail Jim

 

You can use two cooler's just link them together.
