    I just got this car about 2 weeks ago, so I am unfamiliar with the way
    this traction control is suppose to work and sound.

    Here's what I have: When starting on a slippery surface, the traction
    control light (TCS) comes on and flashes while engaging. When it engages
    and goes from wheel to wheel you can hear it engaging and unengaging but
    it sounds kind of like a gear grind while this happens (kind of like a
    wratchet on the backswing) that normal-the flashing light and
    gearmesh sound? when driving on a road and I hit a patch of snow or
    somthing, I don't hear any gearmeshing sound, and the TCS light
    illuminates and flashes while the TCS is engaged.

    It all sounds pretty normal. The light flashing you see indicates the TCS
    is actually doing something active at the time. The noise you describe is
    the TCS activating the ABS. It's entirely possible that when driving along,
    you may not have encountered a condition that caused the TCS to engage ABS
    to assist, although the TCS may be limiting engine power at that time.
