  1. According to GM it is. Where do you get your info
  2. According to a GM service bulletin i have, the switch between V8 and V4 is accomplished in 250 milliseconds. So i think you will be OK
  3. Hello, new to this forum. Recently purchase a 2016 GMC 35K with the 5.3 engine. Just to give a different point of view from the posts i am reading. My truck shifts so smooth you cant feel unless you are watching the tach. It also changes in and out of 4 cyl mode where you cant feel it. I just took a 100 mile trip and averaged 20 MPG in 15 degree temps. So i am happy with my AFM.
  4. There are millions of these trucks on the road. Sorry that yours failed, but i dont think its common. What is the dealer offering you in choices.
