I have a new problem with my C7 non Z-51 automatic transmission. While I have the cruise control set for 55 (or so), when the car attempts to accelerate just slightly, there is a significant rattle as the engine RPM's go between 1350 and 1500 RPM. It quits above 1500, and below 1350, but is very consistent and repeatable.
It does not matter what drive mode (Eco, Weather, Touring, Sport or Track). It does NOT happen when I am in manual shift mode, if I shift manually, it does not rattle. If I put it into "rattle mode" and shift to manual shift mode, the rattle stops.
Has anyone with an Auto six speed experienced this issue? I reviewed the posts with rattle or noise, and could not find another post similar to this.
