I did the tru cool 40k on my truck. Drop temps down to 150 range.
I also plumb mine bypass the raditor. I might re plumb back through radiator when I install stainless steel lines. In cold weather trans takes for ever to warm up.
Bought cooler off eBay and brackets of performancetrucks.net made install breeze
