I was going horseback riding today. We had three horse in the trailer and we were pulling a steep hill just out of city limits and my new gauge I just installed, I spliced it in the line comeing from the tranny to the cooler so it is the hottest temp posiable, was reading about 245 at the top. The hill was about 2 miles long and I could only get up to about 20 mph in first with it floored that is how steep it was. I averge about 160-165 at 70mph going down the interstate and then in town about 190-210. I was wondering what style aftermarket tranny coolers there are out there for our trucks.

B&M makes some good ones.
