  • Speedo / Tach / Gauges: Correcting Speedometer Reading

    Hi All,

    Our speedometer is the stock commander 1953 w/automatic and the "new" tranny is an early 1962 GT Hawk automatic. The speedometer reading is overstating the actual speed. Has anyone had this problem and, if so, how were you able to solve it?

    Sure, just get the Axle Ratio and Tire size from your '53 and look up the proper Part Number Speedometer Pinion in your 1959 to '64 Studebaker Chassis Parts Catalog for a '62 Flight-O-Matic, and then you can order the correct Gear from a Studebaker Vendor.

    If you do not have the correct Manual you can order one or a CD Rom Disc. of it from a Studebaker Vendor, you will need it for maintenance and repair of your new Trans.

    It may also require ordering a new Speedo Cable and Core if yours is not compatible with the Flight-O-Matic Trans. the length at the very least will be wrong.

      Thanks for the quick response. I'm using the speedometer cable that came with the newer tranny. I'll check with Studebaker's West when they return from the national.

        Or for the time being use your GPS to see how far off it is. Adjust your speed accordingly.
