I can’t really answer your question. There are too many variables between trucks these days. I can address how it worked for me. When I had the 1996 Dodge Ram 1-ton dually, all I could do was disengage the overdrive. It would sometimes kick in and out of OD a lot if I didn’t use it while towing. This is what that switch was for on the Dodge I had.

In the Tow/Haul Mode with the 2004 F-350, I always use it when towing. It really helps hold back on hills and distributes the power as needed for climbing hills. I don’t have a concern about it shifting in or out of O/D. It really isn’t noticeable as it was with my previous truck. I just set it and leave it on when towing, it finds the gear and power it needs; it’s a great feature but I’m not certain just how yours is set up.
