There is a known transmission issue. Look up 18-NA-355. That is the GM service bulletin on the problem. The fix is a transmission flush, replacing with Mobile 1 Synthetic LV ATF HP.

other things that can cause a vibration are bad motor mounts or transmission mount.

Little information and confusing at best. Please explain more fully and tell us how many miles on it.

Would think the caddy Oem struts would be pricey. Probably mag ride or something.
