Thanks, all, those are some good ideas.
FWIW, AEV apparently came up with the idea of using the stock JK trans cooler as a power steering cooler for the Hemi swaps. No reason it wouldn't work with the stock V6 setup.
I'm going to look into this guys idea of using the WK rans cooler & see what it takes. He didn't offer any photos. OTOH, the B&M units look like they'll more than do the job and I like the idea of adding them as a supplemental cooler to the stocker.
