Sometimes you have to let off the throttle and then slowly mash it (if that's the proper way to explain) and almost trick the truck into a lower gear for power. My 4r100 doesn't shift differently when tow mode is engaged, just delays overdrive more so sometimes I can let off the gas just a bit on a long hill and roll into it and get the truck into a lower gear for long hills/heavy tows etc.
Something to try. Also try it without tow/haul mode. sometimes I did that with my 6.0l with the 5r100 I was able to keep it in a lower gear longer by playing with the throttle.
after that you'll need a custom tow tune etc.
