If you are talking about a auxiliary cooler if you are running a automatic radiator you don't need one just because of the manual valve body. But it's always a good idea to run a aux. cooler. The biggest enemy to a automatic transmission is heat. Run it with the radiator cooler. You want to run it thru the radiator first and then thru the aux. cooler. It's a good idea (very good) to use A&A's low band apply manual shift valve body. It helps keeps your toe's where they belong and it's just about $100.00 more.
