So I started having this issue a short time ago and I sent the car to Chevy this past weekend....to no avail it’s still there, I can only assume they just changed the shift knob/boot and went with it since they acted like it was fixed.
It’s really bad under light load on the throttle, in gears 3/4 it sound thes worst, I said to check tranny but I’m assuming they did not....any info is appreciated...still taking it back Monday I believe.
