I'm just baffled that I have it now after having the drivers bank lifters replaced. It's annoying.

Has anyone else notice an increase in DFM vibration after lifter replacement. I never noticed when my truck shut cylinders down until shortly after having the driver side lifters replaced. 21 5.3L 8 Speed 12k miles

I'll let you k ow for sure. My just started out of nowhere.

My.14 Silverado 5.3 just start a really hard 3-2 downshift. Has anyone else experienced this? Any solution. Dealer is closed until Monday. 62xxx miles.
