I might be worried about it shifting at 3500, that's pretty low. I'd take it into a shop and have them adjust it, they have the proper equipment to test the pressure of the TV and can adjust it correctly and not just by feel. IMO you're shifting too low. Back when my car was stock it shifted at 4000-4200 or so. I haven't changed my shift points yet so it's still the same.
