"How-To" Install Aux Transmission Cooler WITH Adaptive Cruise Control by SkookumFord

Hi, ya'll. Longtime lurker here. Have a 2011 SHO w/ ACC. I tow a small trailer, and I've been following BPD's Auxiliary Trans Cooler thread since the beginning. I was frustrated that it wasn't available for us guys with ACC, and decided to tackle it myself.
OK, so this diagram shows the oem installation of the auxiliary trans cooler:
It uses two 'T' splitters in the hoses to split the fluid to both the primary cooler and the aux cooler, then to merge the fluid before returning to the trans. It's primarily these 'T' splitters and associated hoses that occupy the same space as the ACC Radar.
Anyone who's installed an aftermarket cooler knows that this is an unnecessarily complicated way to plumb an aux cooler. I just rerouted the output line from the Primary Cooler to the input on the Aux Cooler, then spliced the output on the Aux cooler into the Return Line on the Trans.
Transmission Output -> Primary Cooler -> Aux Cooler -> Transmission Return
I didn't bother replacing the bypass valve, or buying any of the other oem parts beside the cooler.
The bracket that comes with the cooler interferes with the bracket that holds the ACC. I just cut the extra crap off the cooler bracket and bolted it to the ACC bracket. There's about 1" of space between the Cooler bracket and the ACC bracket. I just filled it with some washers I had laying around.
Put the bumper cover back on today, topped off the fluid, and took it for a spin to check for leaks. Now I can tow with confidence!

Correct. I cut and removed the bottom hose and replaced with new hoses running thru the cooler. Any 1/2" rubber hose works. I bought 4ft and had a little extra left over. And you'll need a 1/2" brass barb hose splicer like this: http://www.amazon.com/Mender-Splicer.../dp/B007ZDNSJK
