slafranca77 Posted October 2, 2021 Report Share Posted October 2, 2021 I'm doing this swap soon on my Denali as well, 725hp/650ft/lb. I've found a site that has a full conversion kit with cross member, flex plate, harness adapter, trans mount, and transfer case adapter for just under 2k combined with a decent. 4l80e for around 2k I'd say 4000 is spot on whoever suggested that price. Let me know if anyone has any updates on this please. Quote Link to comment Share on other sites More sharing options...
dcairns Posted October 2, 2021 Report Share Posted October 2, 2021 Can you share a link to that site? With 150k miles on my truck, I am on my third rebuild of my 4l65. Last time it was the input shaft that gave way. The idea of a 4l80 is sounding better all the time. Quote Link to comment Share on other sites More sharing options...
