One thing to also consider is the orientation of the cooler. IMHO air pockets can make the cooler less effective, especially those type that have a bypass built in, or that's my theory anyway. 
Those were for vertical mounting, but another way would be to mount one horizontal.

goat... I know you wrote the words on the picture but you have the red sharpie in the pic so it looks like you wrote all over your floor and the cooler haha

More air flow the better IMHO, either in front of the radiator fan or add an extra fan just for it.

Thanks. That's my plan. My trans fluid looked more on the burnt side when I bought the truck so I will change this first filter early (maybe 10K?) and I'll cut it open and post pics.

I did mine last year with the TruCool 4454 and an external bypass (I know the 4454 has one built in). Then a few months ago I found codes for my scangauge that will read tranny temps. I haven't had it over 155* yet. So in all honesty, I don't know if my cooler even has been used yet (external bypass opens at 180*). I plan on removing a hose pretty soon to check. Maybe even remove the external bypass altogether...
Anyone remember at what temp the built in bypass opens at?

Its a passive bypass, so its always open but more goes through when its cold. When its hot the flow dynamics are such that the ATF flows easier around the bypass.
I think you'll find even with an active bypass there is still some flow through. maybe 80/20 or something like that. Just feel the cooler and see if its warm or not.

The kit came with 5 foot of hose and the silver brackets you see along with assorted bolts/nuts and some ziptie fasteners. I didn't think that the 5 foot was going to be enough so I bought 8 foot of 3/8 line from Autozone and used about 7 foot of it doing the install. I did not use the line that came with the kit at all. A lot of people feed the new lines through a hole made for the a/c lines but it looked too snug to me so I just went under the frame and back around to the steel lines. I did end up needing a few extra bolts/nuts and washers and since I put in the filter I needed some extra clamps too.

Lots of threads talk about that. I tested just to be sure. I pulled the lines off and put them in a bucket and started the truck and watched which one the fluid came out of. when you are looking at the front of the truck the line going into the left side (passenger) of the radiator is the "hot" from the trans line. The line coming out of the radiator on the right (driver) side is the return to the trans line.
