My roof was making its rattle noise (plastic-on-metal flapping noise) again this morning. I went to the local chevy service department and asked for a test drive with the local tech (Jack).
We went on the test drive and my roof was rattling way (but Jack started to state that "it's going to make some noise"

). Sell a vehicle that doesn't make the noise and when it starts making a noise (it's normal ....)
While on this test drive, I demonstrated the 1st-to-2nd gear shifting problem. Jack agreed that it was shifting a bit rough.
They're going to do some research and let me know when to take my SSR in (again!).
