Fairly simple, mount it where the old one is if you wish, use the metal straps provided and just form them to fit. Just hook your new line where the old was, if you got the thermal bypass make sure you hook that up the right way. I had to get new 5/16 line as the kit come with 3/8 and the stock tranny steel line is 5/16. It fits over the fittings in the kit. That's the only thing extra I had to get. Some change the steel line to 3/8, I didn't. I did mine at the same time as the IC so I removed the center support for the hood latch and put it between the IC and the AC. Some put it in front of their IC, mine cools just fine where it is. Just telling you that if you want to remove that you can.

Yep, that's all there is, it will take you longer to figure out how you want to mount it than anything.

ok wow that is simple. another question what lines is the inlet and what line is the outlet for the fluid? cause if i remember right theres a line that runs from the tc to the bottom of the radiator then to the tranny. then theres a line that goes right to the tranny. right? and which is the inlet and outlet on the new tc? im guessing that depends on how its mounted or does it say inlet and outlet?

Doesn't matter which way you hook up the lines on the tc itself. IIRC the fluid running towards the tranny cooler is the front steel line on the tranny. You only need to know that if you are hooking up the thermal bypass. You are right on the way the lines run.

No problem, you'll like that cooler. My tranny hasn't seen over 200* pulling the trailer in my pic in 90+ degrees in OD.
