    My brother replaced the odo gear on our '93 SL1, worked for awhile, then
    intermittently fails, oh well. They are tough to get to and tougher to keep
    reliable, it was a "feature" of 1st gen Saturns. There are a few places
    online to buy this gear cheap too.

    Just out of curiosity, is the gear that is failing in the
    speedometer/odometer or transmission? I am trying to understand what is
    failing and possible causes. Is there something that is binding that causes
    the gear theeth to strip? Is there a worn bushing that is causing the gears
    to not mesh properly?
    In other (old school) speedos, there was a plastic gear in the transaxle
    that drove the speedo flex cable and in turn screwed into the speedo
    indicator on the instrument panel. I saw a few flex cables over the years
    that were either worn or needed lube to keep them from making noise and
    eventually binding that chewed up the plastic gear in the transaxle. Saw a
    few speedometer units also in the instrument panel that the input shaft
    started to stick and needed to be re-lubed. I never had to open up a speedo
    unit to fix anything inside. If you do open one - be careful not to get any
    iron debris inside. there is a very tight clearance between the iron bell
    driven by the speedo cable and the driven magnet. Iron filings or any
    ferromagnetic debris will get sucked into the magnet and mess things up.
    I use automatic transmission fluid for all oiling. It doesn't gum up like
    motor oil does.

    Hey Oppie. The gear in question is a tiny plastic gear inside the dash
    behind the guages. Its a be-yach to get to and the tiny gear is no fun
    either. once replaced, there is a 50/50 chance that it'll remain working
    forever. The gear is actuated by the reset button for the odometer. One
    major cause is old age but also pressing the reset button will further cause
    the tiny plastic gear to break as well.

    Thanks for the clarification.
    Does this gear drive both the trip odometer AND the main odometer?
    If pushing the trip odometer reset exacerbates the problem, it's possible
    that the reset pawls from the button are not retracting all the way when the
    button is released. This might cause jamming of the odometer advance
    mechanism and a broken drive gear.
    I had a car that had such a problem and it was easier to use a gps to keep
    track of speed and distance. The readings were, of course, volitile and
    distance readings were lost on power off. I changed oil based on color
    rather than mileage...
