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.

Did they do it with an oil change or you had a complaint about it? I seen some tsb documents and they are very unwilling to perform an update even if my truck year and build date fits the tsb

Brought it in under warranty as an issue / complaint. I knew from reading this forum that others had the same issue. Some people had reported improved driving after recent updates. So, I told the service manager the issue, what identifying and troubleshooting steps I had already done (a lot), and a recommendation to check for (software updates) based on previous resolutions. I didn't have any specific TSB’s. I didn’t “tell” them to do updates. Rather, just gave a clear recommendation for them to be the first thing to check.

If there had not been available updates, or if they updates didn’t fix it, then I would still have it there as a warranty service for them to identify and fix.
