So I installed a Hayden 402 transmission cooler that was somewhat small and easy to place. The best thing you can do for yourself is get a Hayden 397 fitting. This fitting will allow you to install the cooler without cutting into any lines. I installed my cooler on the passenger side (PS) of the front. I took off the radiator fans and front bumper cover. I oriented the placement of the cooler in front of the PS vent in the bumper, at least close enough for air coming through the vent to catch a majority of the cooler. I un-plugged the upper radiator trans cooler line, I then installed the fitting into the trans cooler port on the end tank of the radiator so then you're left with two pipe ends which are perfect for the tubing in the kit. I then used the included zip ties to run them through the cooler, condenser, and radiator. Removing the fans just help situate these, you don't have to but it would help with a larger cooler. With this setup you then run the cooler after the radiator, as I learned above. Pretty easy to do.
