What Fred is referring to is the transfer case. You are referring to the transmission overheating. Two different things

I am not at all aware of the logic behind, what I assume is since it always checks where to supply more power it over heats (working some what similar to D mode). If the central diff is locked, its not overloaded. I cant think beyond this technically. Or might be some flaw in the factory design.

But for sure ready to try different options and wanted to overcome overheating problem otherwise it takes away the fun and I start worrying about when I will encounter the problem.

Are you still having ATF overheating after installing the fan and driving in tiptronic?

@Lakshmi Narasimhan I drive with 4hlc since i started with intermediate drives and I feel the power on the long climbs…. 50/50 split works for me and I haven’t had the transmission heating issue for last 32 drives!!!!

My transmission heating problem was due to some dirt stopping the fan from running, once that was fixed there is no more trans overheating problem. I also tried 4HLC which also worked in churned up sand very well.
