Tech bulletin for Tahoe vibration

Q: I have a 2015 Chevy Tahoe LT 4WD. I get slight vibration at slow speeds (almost feels like the car is hesitating) and it sounds as if I am likely in excess of a rumble strip if I do it on the freeway. It only does this when there is a specified pressure (light stress) on the gas pedal. If I press more durable — or let off — the vibration stops.

The regional Chevy seller explained it is the torque converter shutter. They explained it is incredibly popular on these cars and he sees a ton occur in close to 75-100k miles. I have 133,000.

Is this a popular challenge with the 2015 Chevy Tahoe? The supplier stated given that it has more than 100K miles, it is likely to cost $6,000 to substitute the transmission with a new 1.
