Bxnanaz replied to ata3001's topic in 2014-2019 Engine, Driveline, & ExhaustGen Vs aren’t known for lifter failures. Not nearly as bad as IVs. The only thing that will really keep your lifters happy is keeping up with your oil changes.
Got the truck back already. They “could not duplicate”, but found multiple TCM updates, 1 ECM update, and trans was 1/2 quart low. Still has a rough downshift into 2nd. Updates did actually make truck much more enjoyable now. Truck doesn’t stumble and bog itself like it used to. Would recommend going to dealer for updates to anyone with a 5.3 6 speed. Dealership was very professional though, and told me I’d i still had issues, bring back the truck with my trailer hooked up to it and we’ll see if we can duplicate it.
Have an appointment at the dealership for my ‘17 5.3 6 speed having extremely harsh downshifts into 2nd and 3rd when in tow haul, or manually shifting. Tech is scheduled to do a ridealong. Will keep this thread updated to let y’all know what happens.
