    Transmission Speedometer Gear

     



    I need to find out how many teeth I need on the gear in my transmission for my speedometer to read accurately. I have a turbo 400 transmission. 29 inch tall Mickey Thompson tires with a 456 gear ratio in the rear end. Can anyone tell me what size (how many teeth) gear I need?

    a 15 tooth drive gear with a 45 tooth driven gear is as close as you can get
