Post Speedo

I need some help with my speedo gears, i`ve looked at charts and it just confuses me, math isn`t my strong point. my cutlass speedo is way off, the car came with 2.14:1 gears, and the tranny in it, i have no clue what it came out of, so i don`t know the gears it has, it`s a turbo 350 lockup. my rear now has 3.23:1 gears, so any help would be appreciated, my rear tire size is 235/60R14`s, i would just like to go to GM and get the right gears. I have a trip coming up and would like my speedo to be right for the first time in years, can`t afford anymore speeding tickets lol, thanks a bunch, DV.

This has a speedometer calculator which does the work for you. You will need to pull the speedometer cable and bullet housing out of the transmission so you can count the number of teeth on the drive gear on the output shaft. Most of the time you can tell by the color code of the drive gear. The color code chart is listed on the above site. If discolored by age or fluids....just countem.

Just plug in the numbers and BAM.... home free..
