Does anybody have a vibration feeling ?

Accelerating on ramp or highway speeds I would say between 50 and 65 I will sometimes intermittently feel a vibration rumble feeling almost like a misfire that lasts a few seconds. Anyone else experience this? Any known fix? Thanks.

I get the vibration right when the tranny wants to start it’s surging behavior.

Yep, seems to be a common thing on the SO. Definitely a software issue. I just had the latest ECM/TCM updates installed at the dealership this month for it. Sorry I don’t have the specific updates performed. The dealership identified them though (I didn’t tell them which updates to check for).

Post software updates, the truck is much smoother on slight throttle at those speeds. A turbo engine running high PSI like the hurricane can be hard to get the throttle mapping to be butter smooth across all ranges. It’s much better after the latest update.
