I know what he was asking about, an external cooler. ...
Yeah, I reread it and now see it the same way that you do. I'm not quite sure what made me think relocation on the first read. Maybe beer.
What kind of gearing do you have? How fast are you going on the hwy?
I drive a towboss with 4.30 gears and I know mine runs at a higher temp at 70mph than the same truck with 3.73 due to the higher rpm range. The proper test (65mph, no load, after hitting OP temp) can't be done with my truck without some modification to the speed.
Good point to mention. I have a similar thing going on. My recommendation is 1900RPM rather than 65mph.
