2016 GMC sierra 6.2 with 97k miles-still under warranty
Valves started tapping so he called your office about afm delete and trans cooler delete,( I have been telling him to do them for 2 years) and talked to a lady.
Since it was still under warranty, he decided to see what they would do.
They replaced a bent push rod and all the lifters, extended the warranty on that work for 2 years 20k. They did not do an oil analysis for metal even though they were asked to
Is it time to trade? Keep and drive?
He is looking at a 2018 Denali with 18k that will come to you for the fixes.
