There are no "parts".... you have to reprogram the computer. A used Hypertech programmer is a cheap way to do it. You could also buy LT1_Edit and change it yourself, or you could have a "mail order" tuner do it.
Its not like the old days when there was a gear on the tranny output shaft, and a gear on the drive cable that could be swapped out based on gear ratio. Now you have a reluctor ring on the output shaft, a magnetic pickup "sensor" and a feed of pulses to the computer, which bases the speedo output on the programmed gear ratio and tire diameter.Fred

Fred is right........Up though 93 the speedo was done with gears. 94 and later use electronics. You'll need a reprogram.Originally posted by redbird94
