==Estimating transmission ratios== A way you can get a ballpark figure for what the '''transmission ratio''' is - if the car is drivable, and has an accurate tachometer and speedometer: *Drive the car at 1000 RPM (you can use a different RPM and convert it easily) in whatever transmission gear is 1:1. :Note the speedometer reading. *Then put it in whatever transmission gear that you want to know the ratio of, and drive at the exact same speed. :Note the tach reading. *you move the decimal point three places to the left, that's your transmission ratio. Example: If the tach says 3200 RPM, your transmission ratio is 3.2:1. ==Resources== Also see '''[[Gear ratio check]]''' for estimating '''rear''' gear ratios.
