Actually, unless you live in the tropics, you WANT it in series, as Joe posted. Like this: transmission> external filter> supplemental cooler> in-radiator (stock) cooler> transmission. When it's truly cold, the stock cooler will warm the ATF on its way back to the tranny. With an add-on cooler
bypassing the stock cooler altogether, the ATF may not warm sufficiently to allow torque converter lockup in cold weather.
In short, the function of the stock cooler is not so much to literally "cool" the transmission fluid as it is to
maintain its temperature within normal operating range.
As I said, Capuano, opinions are apt to vary on matters where there are no absolutes. Confused yet?
