Update: So I dropped the V off at the dealership for the hard shifting and a CEL, the code came up as what they told me is a "lean" code, there was something loose that had something to do with the air intake. They fixed that under warranty and that also got rid of my hard shifting.
My next project is the passenger door speaker, I have the Bose system which I'm sure is stock, as long as I can remember the speaker has sounded blown, but after researching some stuff I notice a lot of comments regarding this problem being just a GM problem, now that I've been really listening I think mine could also just be one of those annoying rattle and the speaker might be fine. What do you recommend I do to pad this down and is it a small enough project for me to accomplish by myself, as you can probably tell I have no experience with this type of work. Thanks for your time.
