Adding a transmission cooler is a very wise decision, if you ask 10 different people what one is the best, you will get 10 different answers. As for how or where to mount the cooler, they come with plastic zip strips to mount them to the existing radiator. Just mount it on the outside of the radiator, not between the radiator and the engine. Also, make sure you run the lines so the fluid goes through the radiator first then through the cooler. Buy extra transmission hose, the kits usually don't come with enough hose. Good luck!
