transaxle and rear wheel drive

the gearbox is used to convert the torque from an engine to the wheels by using different sized gears. the reason for this is because we need more torque when taking off rather than when we are driving at 50 kmph. the manual gearbox enables the driver to pick the optimum gear ratio to increase torque for driving.


shifting:






a 5 speed manual gearbox will have 3 selector sleeves (1 for every 2 gears) the selector sleeve will slide the over the baulk ring and engage the gear.
