I have a 2005 Hyundai Accent GT (manual) that rattles obnoxiously
during acceleration. Once cruising/shifting rpms are reached, it
disappears. It sounds like it is coming from outside the cab (under the
hood maybe), but I have not once heard the sound while listening with
the hood up and manually revving the engine using the throttle cam.
This makes me think it may have something to do with the transmission,
because as soon as I get in and drive off, its there again. Anyone with
a similar experience?
