in cool temps its not going to be a problem ether way. its when your pulling a long mountain pass in the middle of August with the outside temperature around 100 deg. your radiator cooler is already near 200 deg engine temp. then your trans starts to heat up pushing the engine temp up more then external cooler has to take care of both sometimes not being able to handle it. I would think its a good idea to bypass the radiator cooler as they did. that keeps the trans heat out of the radiator and in the axillary cooler.
last summer with temps near 100deg. I had to go up a 5 mile steep mountain pass with my 2010 GMC 1500 with tow package and a 27' T/T. the towing part was not a problem, I was able to travel 60mph easy. but as I started up the trans temp started up soon we are a little over 200. now the engine is starting to heat up, it was kinda like a nuclear reaction. by the time we hit the top the trans was about 240. i'm thinking about getting a larger cooler with a thermostatic fan and not use the radiator cooler.
