  1. What do you mean by tuner? The dealer had a transmission man with 20 years service they told me to get rid of k&n filter.
  2. The tach gies over 4,000 , I'm assuming it's first. this is at 50+mph.
  3. My 2018 Sierra SLT 4x4 crew cab with 33,000 miles down shifts to first when coasting down long grades, and using cruise. Sometimes when the grade braking is engaged and when it's not engaged! No codes, took it to dealer and they said all was normal. this Is the second time to this dealer. Anyone had a problem like this. Great truck other than this one problem
