Northwoods Snowman

I picked up a trans cooler from a mid 90's Chevy 2500 and it's VERY similar to the B&M 70264 cooler (dimensions and design.) I found by monitoring the in/out temperatures of the ATF lines from the trans that the OEM aux cooler just isn't adequate for low speed operation. It seems to work well enough when running at highway speed with the torque converter locked but start towing a trailer around town or loading up the drivetrain off-road and I've seen outlet temps at 280*. I have more details on this in my build thread but here's how it turned out.
