Is there something wrong with the Allison transmission in GM pickups?
Other than it doesn't have 4 overdrive speeds mostly useless for towing?
Other than the gasser trucks haven’t had the Allison option since the 8.1L days, nothing is wrong with the Allison.
GM calls Allison: "We need more speeds... consumers want speeds!"
Allison: "Why?"
GM: "Because Ford has more speeds..."
Allison: "But Ford uses 140 cubic inch engines..."
Allison does not build transmissions for GM. GM licensed the name for marketing reasons.
I have an actual Allison 6 speed in my motorhome. I really wish that it had one or two more gears. You do not notice the gear spacing much when lightly loaded but as you allude to it is much more important when heavily loaded. Most people buying a 3/4 ton or up expect to load it heavily at times. My motorhome is always heavy.
