-'''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- is to drive the car at 1000 RPM (you can use a different RPM and convert it easily) in whatever gear is 1:1.
-Note the speedometer reading.
-Then put it in whatever gear that you want to know the ratio of, and drive at the exact same speed.
-Note the tach reading. If you move the decimal point three places to the left, that's your low gear ratio.
-'''Example:''' If the tach says 3200 RPM, your ratio is 3.2:1.
-Also see '''[[Gear ratio check]]''' for estimating '''rear''' gear ratios.
