Hi all. I have a 2005 Yukon XL Denali and wondered if anyone else has had success doing a radiator bypass for the tranny lines, and just using an Aux cooler on the front? Issue 1: From the factory...

The thermal management 'SYSTEM' has more to do than you seem to think about...
Also, your profile says Colorado, so extreme cold...subzero even for long stretches of time
By changing the thermal management system by not having the ATF go into the main coolant radiator...you might have ATF that is too cold during those subzero times
The sizing of both the ATF external aux and the ATF internal radiator in the cold tank of the main radiator accounts for both the cooling and heating of ATF AT SPECIFICATIONS during all aspects of your vehicle...including using it as a TV towing heavy (up to the specification limits)
Ever notice semi's running in subzero ambients will cover a portion to totally cover their radiator intake/grill ?
Recommend keeping the routing into the main radiator and installing another or bigger ATF Aux external radiator
