Americas Idle Vibration. Annoying

[Mountain4x4]

They modified these transmissions with a low stall, heavy duty torque convertor. Wonder if that contributes. Nothing I ever noticed, but then again I only drive heavy duty 4x4s.

Setting up an appointment to look at it again. No difference if AC is off. Still have the vibration. It's way worse on an incline to decline.
As a person that has always hated the Start Stop feature, It is very welcome with the vibration issue.

Will update soon.

I have the same issue, notable vibration on idle. Goes away when AC if off!

mine definately does not do that. I think you need to go to the service guys.
I have had the best experiences with the service guys at warner ineos in salt lake city.
if your guy can't figure it out i think its worth a roadtrip out there.
Maybe join the grenadier fest in october and have them look at it then?

Both of my loaner have done this too.

It’s the tq converter. The ac affects it likely because most systems up idle for AC.

I picked my Grenedier up today and about ½ way home in stop and go traffic, I too noticed a vibration. If I put the shifter in neutral, the vibration would go away. I turned on the auto stop/start feature... , it was LESS annoying than the engine vibration. Also, less worrying. With the vibration there was increased engine noise and I believe I needed to apply more brake pressure to keep the vehicle in place. A torque converter not properly disengaging would cause every one of my 3 symptoms.
