Well you don't change just 1st...you change the entire gearset which includes the cluster gear, 1st and 2nd speed gears.

While the trans is apart, change the speedo drive gear from the black 8-tooth gear to a yellow 7-tooth gear. Then you can run the red 21-tooth driven gear for an accurate speedo with 3.73's.
