Just by the speedo gears, around $20.00. If you go and look in the tech articals it will tell you what gears to use.

For a 700R4 automatic you need a 15 tooth and 45 tooth speedo gears. They go in the tailshaft of your transmission.

For the speedometer, you have to replace it with the one you want.
