As far as the work truck transmissions failing around 100k. Yes I've heard that about the 4L60 and talked to the local transmission shop when I bought my original Suburban. Their recommendation was to avoid the 1/2 tons with 4L60's and go with a 3/4 ton since they come with the 4L80 which is supposed to be much more stout. It was one of the reasons, but not the only reason that pushed me into a 3/4 ton.
Our trucks are 3/4 ton. I don't know if we were unlucky or if others have encountered this but our non HD 2 wheel drives came with the 4L60. Still great trucks we just encounter heat issues around 100K miles.
