Actually, the cooler that is on the steering rack by the cat is an oil cooler. The tranny cooler (stock) runs throught the bottom of the radiator. If you want to add a secopndary cooler you can do that but run it in series with the stock cooler.

 

Both a AUX tranny cooler and an engine oil cooler will help "chill" your car not to mention extend the life of your engine and transmission.
