I wouldn't recommend reduced transmission cooling, even during the winter. Automatic transmissions don't seem to lose any fuel economy when running cooler, but they lose longevity when running warmer.
What's with the fresh-looking stain on the ground?
That's just water on the ground...I was hosing off all the crud and dirt that had built up behind the dual auxiliary coolers.
With the dual aux coolers along with the factory radiator transmission coolers...I think I should be okay. I still have to plumb in my transmission temp gauge setup so I can keep an eye out on those temps and what mods work and don't work.
