The job of an Automatic Transmission Perth is to let the engine operate in its narrow speed range while providing a wide output speed range. Without a transmission, cars would be limited to one gear ratio. This ratio would have to be chosen to let the car travel at the desired top speed.

The Auto Transmission Perth uses gears to make more effective use of the engine`s Torque and to keep the engine running at an appropriate speed.

The Auto Transmission Perth uses a Planetary Gearset,to produce all of the different Gears, Set of Bands to lock parts of a Gearset, Clutches to lock other parts of the Gearset, Hydraulic system to control Clutches & Bands, Gear pump to move Transmission fluid around, just to name a few.

The Torque Convertor sits between the Engine and Auto Transmission.

The Torque Convertor is a type of fluid coupling, which allows the engine to spin somewhat independently of the Transmission. If  the Engine is turning slowly, the amount of torque is very small,(sitting  at the lights), when you step on the accelerator the engine speeds up and pumps more fluid into the Convertor, causing more Torque to be transmitted to the wheels and so you increase speed and move through the gears.

This simple outline tells you that understanding and repairing a Transmissions are not simple and straight forward, and it takes many years of experience to be able to diagnose and repair the Transmission, of which there are hundreds of different kinds, all slightly different.
