The two radiators you see are: One is the engine radiator, for cooling the fluid in the engine. The second one is the Air Conditioners condenser, to make a long story short it makes the Air Conditioner work. The tranny cooler is built into the engine radiator. There will be two hoses from the transmission to one side of the radiator and there is a sealed tank inside the radiator that cools the transmission fluid using the radiator fluid. Too add a additional tranny cooler the hoses will be removed from the radiator and a T fitting added then there will be a cooler mounted in front of the Air Conditioner condenser and behind your vehicle grill. Any decent mechanic or radiator shop can do it. it's actually purty easy and I've done it myself before. They make kits for each vehicle that makes it even easier.
