Manual Transmission/Transaxle: Testing and Inspection

Calculating Overall Ratio "i"

Example





i = Z2 : Z1 *

iG = gear ratio = ZG2 : ZG1 = 29 : 39= 0.744

iA = axle ratio = ZA2 : ZA1 = 61 : 18 = 3.389

itotal = total ratio = iG x iA = 0.744 x 3.389 = 2.521

* Z1 = no. of teeth drive gear, Z2 = no. of teeth driven gear
