Up here you want hot transmission fluid to go to the external cooler, then radiator tank then back to the transmission.

By tranny cooler I meant the one integral to the radiator. I think I could hide an auxilliary one somewhere where it wouldn't be too obvious.

No slip accounted for. What do you think of this?

Yep, knew that. I wonder if the 4.11 vs 4.10 (Dana vs Eaton) would make a difference. I was told that the front turned slightly faster in these trucks to help keep them more stable, is that true? maybe that would be lost if I swapped to the Dana? Had a friend who bought a 4x4 without testing 4x4. Needless to say, he was stumped when it snowed and his truck was less stable in 4x4 than 2x4- he had a significantly slower ratio up front.
Thanks for your advice, nice to talk with someone with a similar rig who's been there before.
