While driving my wife's 2016 Yukon Denali yesterday, I noticed a vibration which I initially thought was the road surface. As we were in the rolling hills, it was not a constant event. The vibration could be felt in the steering wheel and the seat and only when going up hill. Eventually I noticed the tachometer reading increasing about 100 rpm each time I felt the vibration.
Has anyone experienced any thing like this? Is it transmission slippage? Torque convertor?
Thanks for any insight. Car has 29,000 miles
