Mark,
I agree the in-radiator transmission cooler is indeed a cooler, but as part of the radiator, it will be warmer than his separate cooler.
Are you assuming that, or have you actually measured the temperature in the cold side of the radiator in cold weather?
I've measured the temp, and while it is warmer than air temp, it is only by a couple degrees. The radiator is so efficient at cold temps that the coolant in the cold side of the radiator stays near the ambient temperature. It is NOWHERE near engine temperature. So if you route the lines backwards you severely compromise the cooling capacity of the system without improving the cold weather operation. It's a bad trade off.
