The 8-speed transmission in the 2016 Yukon Denali is not dependable. I wanted to get rid of it. I miss the V8 engine but the Acadia Denali is quite comfortable. I thus must leave this forum. I do like the GMC brand over all other GM brands. It is a luxurious brand without being pretentious. I got rid of an Escalade because I felt embarrassed in it. My passengers did not enjoy being bounced around in the Yukon. The 3rd seat legroom was a joke. Again, I will miss the engine but not the transmission. That 8-speed is a failure. Shifting from first to second always caused an unnecessary vibration. I anticipated future trouble. So I dumped the vehicle.
