dealership flushed transmission out twice and put the mobil fluid in it. What a difference. So far good to go.Thanks for the help guys.

Hello to all. 3 weeks ago I started to notice a vibration in the steering wheel. I took it to my gmc dealer and they performed a 4 wheel alignment. After leaving the gmc dealer I noticed that I still have the issue so I went to my buddys tire shop and had all 4 tires rebalanced. I still have the issue but what I have been noticing is that when the trans temp gets around 165 and in overdrive I get the shutter effect. As soon as I put it in 7th gear the shutter goes away. I have a 2016 gmc sierra 6.2 liter with 38000 miles. I just called the dealer and explained what Im seeing and they said they never heard it before. I have a appointment with the dealer this coming saturday. Any hel or info before I go to the dealership I would appreciate it. Also I do not get a check engine light. Also It only happens at speeds of 55 to 75mph.

so your telling me that your unit will say GMC on both splash cluters ? Have navigation and the icons for projection and android auto?

I purchased an hmi 2.5 front Eynon GMC dealer to get navigation. They installed the unit and now the 8 inch screen say gmc denali and the small cluster driver info says CHEVY. I told them I wasn't happy with this so they refunded my my money. I also purchased a hmi 2.5 from infotainment.com and had the same issue with chevy icon showing up on the drivers small cluster. What I want is to have projection and or android auto on my screen so I can use either 1 to get google maps or waze. MY current HMI is a 2.0. My vehicle is a 2016 GMC sierra slt. Can you help me ? I just want both clusters to say GMC and have the ability to use projection or android auto to get maps from my iphone. Or should I get your nav 2.5 hmi?
