Hi everyone, I’m new to this forum and I just want to get a good idea of how many miles everyone’s getting out of there 14-18 5.3’s / 6L80 combos and what type of maintenance y’all are doing to get there. I have 90,****** now on my 2016. I follow my service schedule to a T. Trans fluid and filter every 22,500 and engine oil every 4000. What’s everyone else do to get there trucks up to high mileage
