    IMO, you should be aiming for perfect odometer gearing, and then use the built-in calibration after that point to fix any error left in the speedometer reading, as the odometer is geared directly to the cable and doesn't rely on a spring, etc like the speedo does.

    I've found in most cases, once the odometer is reading accurately, you can get the speedometer reading correctly as well using the calibration lever.

    (PS: Also, on the R154 the ABS speed sensor ring is a part of the speedometer drive gear, they are not two separate parts).

    Seamus I <3 you. I think you just saved me a whole day of effing around.

    Back to part2 of my original question.

    What speedo gears are in my trans?

    And Jeff, your odometer points are duly noted. However, my instrument cluster is a HUGE PITA to try to remove due to the 2 extra instruments.

    Yeah, if you don't want to remove the cluster, the correct speed is probably more important than a correct odometer, heh.

    Answered that already in my first post, most likely 35:10 going by the tire sizes and gearing for the mk3 punched into that spread sheet.

    When using those long needle nose pliers to pop the snap ring off from the top of the W58, don't drop the snap ring trying to put it back on.

    Just don't.

    Yeah having a long magnet pick up tool on hand would be a good idea.

    Oh Brian, if you want to know for sure, just jack up the backend of your car really high and pull out the speedo gear. You shouldn't get any oil leakage if you get the rear high enough. The output shaft gear is stamped on the speedo gear too. They can be a little stuborn if they've never been out, sometimes you need to pry them with a flat head a little.

    So, Jeff can you order this 9 tooth gear? I'd definately be down for one.

    FYI: I just bought a metric 'ratio adapter' to fix my speedo, about 65-80 USD at most speedo shops. They can build them to a ratio you choose.

    I just went through this myself and decided I'm going to have to live with the 35-10 that my tranny has, it's the highest ratio (matched) that they came with as far as I could find out.

    here's a thread I found http://forums.celicasupra.com/showth...ht=driven+gear

    Someday I'll have a 4.10 and it'll be closer, but for now I'll just run the gps to confirm what's what and live with it.

    I didn't realize you'd actually installed it yet. Did you feel the need to brace it or anything?

    thx

    No bracing, just let it hang there. It can also be set 'in-line' instead of offset by undoing the 4 screws and rotating the cover.

    I have been looking for answers. I have the 35.10 and it runs 12% slow. I calculated that I need a 30 tooth, but using part numbers found here, the closest match is 31-10, which I ordered. The diameter of the 31 gear is 2.5 mm smaller than the 35, so it does not engage the drive gear. I ordered the 31-10 gear with the part number 33403-29145. Anybody go any ideas? I have a w58, but don't know for sure what it came out of...is there a way to tell?

    Thanks,
    Dan B

    Update for 9-tooth driven gears:

    33403-29205 - Gear, Driven (35:9=3.89:1)
    33403-29195 - Gear, Driven (34:9=3.78:1)
    33403-19325 - Gear, Driven (33:9=3.67:1)

    Interesting 10-tooth option (used with the larger drive gear):

    33403-29185 - Gear, Driven (36:10=3.60:1)

    33481-22030 is the 10-tooth drive gear typically used for 31-33 driven tooth gears, and is correct for the driven gear you ordered.

    33481-14031 is likely the 10-tooth drive gear that you have, and is typically used for 34 to 36 driven tooth gears.

    Last update to this, for anyone still interested, I put together a list of the part numbers I am aware of for the 2nd generation (aluminum case) W-series transmissions. Should be applicable to the J160 and possibly the TL70 as well.
