"Can of screws in tranny sound"
If that is the sound of your tranny, go directly to your dealer. Do NOT pass go, do NOT collect $200. Seriously, that is not a good sound to hear from a transmission. Maybe it's something simple, but best not to take chances. If you have metal floating around in there, it will cause damage to other parts, and could get expensive in a hurry. Good luck and keep us posted...
