No one has mentioned adding an aftermarket trans cooler??? I don't tow and my trans temps get high already! I say TruCool 40K remove bypass and add inline with crappy factory piece.

Probably because they were towing in OD. With the gears he has and a 33" tire he can tow in 4th all day long and probably be at the perfect rpm around 65mph.
My buddy's stock avalanche has got plenty of towing miles on it chasing pipeline work pulling his 28' travel trailer in 3rd(4l60e) with no problems and the 6speed has bigger clutches than the 60e.
Do you have any more details on the failures? I'm really wanting to do this swap but I don't want to have to worry about towing.

I say 4.10s, having the same 6.2/6L80E/3.73/33s setup as Phil does. He is 100% correct imho.
If you are towing in too high of a gear, is it visible in the trans temps before you cause any real damage to the internals? My NHT truck hasn't even noticed anything I've put behind it yet (~2500 pounds) so I just want to know what to look for once I hook up something closer to my tow rating and go 3000 miles with it.

I have factory 4:10's and roll on 35's most of the time and love the combo! Now I do have a converter and can not attest to low rpm questions in 1st-3rd gear but when converter locks mine doesnt downshift on any hill/bridges! When pulling camper it does a good job any tranny temps stay below 190 as long as I'm not tring to out run a diesel pulling a trailor
All this is done in drive cause I still have not got my tow haul button working
Hope this is helpful as I hAve cam also?!? I have a towing vid in multimedia towing my camper that about 7,400lbs

Honestly I wouldn't touch your gears when you have a 6 speed. Just tow in 5th on flat land, and keep it in 4th when approaching a hilly area. For my 5.3 the optimal towing rpm is 2400-2600. Being that you have a 6.2 your ideal rpm may be a little lower. If your un happy with the 3.42s and 33s when you put them on, then switch to 4.10s.
