Manual Transmission/Transaxle: Testing and Inspection

Overall ratio "i", calculating





Example:
i = Z2 - Z1 1)
iG = Gear ratio = ZG2: ZG1 = 31: 37 = 0.838
iA= Axle ratio = ZA2 : ZA1 = 37:9 = 4.111
Overall ratio = total ratio = iG x iA = 0.838 x 4.11 1 = 3.444
1) Z1 = No. of teeth driving gear, Z2 = No. of teeth driven gear
