Clutch & Gearbox Service & Repairs - (02) 9662 1458

An automatic transmission and a manual gearbox accomplish exactly the same thing, but they do it in totally different ways. They differ in that the manual gearbox locks and unlocks different sets of gears to the output shaft to achieve the various gear ratios, whereas automatic gearboxes use the same set of gears to produce all of the different gear ratio's. Gear ratios are what allow a car to reach a high rate of speed or climb a steep


Without a gearbox, cars would be limited to one gear. The ratio would have to be predetermined to allow the car to travel at the desired top speed. The vehicle would not last very long without a gearbox, making it all the more important that your vehicles gearbox, is always maintained by a reputable company that specialises in gearboxes.
