Upgrading trans heat exchanger to an oil cooler

I expect lower temps, and no worry about contamination.
I'm using those coolant lines for a Webasto coolant heater for cold mornings.

I find the tourque rating increase interesting, because when I was spec'ing out trucks I was told any engine over a 1650 Tq rating had to be liquid cooled. Maybe that was just a Paccar thing, cause both KW & Pete said the same thing...that was back in '08.
