I expect you've noticed there is not a lot of room to add stuff under the hood. The easiest space to put ATF coolers is between the radiator and a/c condensor, coolers for this spot can only be 3/4 inches thick. The available space is almost the size of the radiator. The down side to this location is the cooler is 75% effecient there. Look at Perma Cool & B&M web sites for specs.
