i just bought myself a 2006 BF Fairlane and it seems to have a rattle noise when cruising or light accelerating through 2nd and through 3rd as soon as it gets to 4th its back to being whisper quiet again, there isn't any vibrations or shudders and it doesn't seem to be adversly affecting the vehicle either and it still shifts normally it just sounds like an old bus when cruising around town

oh and even though this isnt the right area im hoping this will save me from making multiple posts but every time i drive on a bumpy road the damn car starts beeping at me as if to say "ding ding ding you are driving on a bumpy road ding ding ding" and no warning lights come up on the dash but "ding ding ding" what the hell does it want? anyway to shut off the notifications??

Possibly exhaust heat shield ? BA & up commonly have that issue. Tap it & see if it rattles.
A few large hose clamps wrapped around it does the trick.

As for the beeping, I'm thinking faulty seatbelt censor warning ?
Plug all seatbelts in & drive on bumpy...?
