    It seems that when ever my battery gets to that low point and I shift into
    reverse it clunks really hard. I was wondering does anyone might know what
    is draining the battery?

    I have a 94 SL2 Automatic with 125,486 Miiles on it. I had the alternator
    replaced last year and also did oil changes, automatic transmission fluild

    Does anyone have any ideas?

    Check glove compartment, trunk light, something in cigarette lighter socket.
    A bad ALT can have a bad diode and drain the battery. Only way to check is
    a amp meter between the battery cable and battery. See how much of a drain.
    The battery could be going. Had one on my wife's 300m die in 4 hours.

    How old is your battery? Maybe it's dying of old age.

    I'm a wondering, what in the wide wide world of sports does the battery have
    to do with a clunking when going into reverse????

  5. Saturns have a wonky transmission setup. They rely on electronics to
    shift and control the automagic tranny, and believe it or not, one of
    the early signs of impending battery/alternator doom is in fact the
    automatic transmission doing weird things. I have a manual so I never
    experienced this, but pretty much the first thing after checking /
    changing the fluids is to look into the charging system.

    Problem being, reverse troubles are also a sign of impending
    transmission doom :(
