Allison was not avalable on Avalache or Yukon/Suburban. Only in Trucks which had 2 inch body lift
In the market 3/4 Ton 2500, preferred transmission?

I knew I should’ve included a link from where I found my info.
Found the quote, I think…
From what I read the only way to get an Allison was certain diesels or the 8.1L. Was there another way to get equipped with an Alli on a NNBS? My buddy’s truck has one on his 13 Silverado 6.2L TD 1T Quad long.

Part of the issue with the Allison is parasitic losses. The 6.0 doesn't give a lot of power/torque "overhead" to lose. The 8.1 and diesels have the torque to spare, so the parasitic loss from the transmission is considered acceptable.

Interesting little factoid. Bigger is better also means bigger needs more tq to offset the additional mass & friction of getting that big bull moving.
