Can an AC Installed make the engine run hotter than before?

Does anyone know how much temperature drop those air cooled tranny coolers lower it? Some one mentioned installing on the return line from the radiator. Any body recommend a location and provide some additional photos.

Tranny fluid can get pretty hot. Well over 200 degrees. The cooler in the rad will hold it at the coolant temp which is an advantage on a cold winter day! I always regarded the air coolers as a convenient way of separating the truck owner from his money and not good for much else. The coil in the Rad is more than adequate.

I guess all the engineer's at the big three don't know squat!
The radiator cooler will not hold it at temp unless it is a very,very cool day. It will cool it off per the differences in each side of the cooler. It will not hold it at coolant temp.

Turbo Hydra-Matic 350 Handbook (HP Books), the ideal operating temperature for transmission fluid is between 175 and 225 degrees Fahrenheit.

The air cooler will drop his over all temps, by how much not sure.
I have never seen a heavy duty truck not have one installed.
They will make a radiator run cooler over all.
Is it the answer to his problem, I don't know but it want hurt to install one.My 700 r4 had over 100,000 miles on it when I pulled it out for the 6.0 4l80e swap.
