Did chevy ever diagnose this common issue with the 2014 Traverse? Mine specifically bumps/jerks when accelerating up hill. It also sometimes slightly bumps when sitting in park, with the rpm needle slightly shuttering.
It technically has one. It's in the tank. But it isn't serviceable. Is the check engine light on? Depending on mileage I'd do a few things. Clean Throttle body and change plugs and drain and refill trans. Those may solve issue. Simple things first
