How Automatic Gearboxes Work

An automatic gearbox consists of four main parts:
  • Torque converter
  • Valve body
  • Gear lever
  • Mechanical gearbox

Symptoms of Failure

Getting water in the gearbox, overheating, limp mode (Safety Mode) and clutch slippage cause the friction surfaces to breakdown within the gearbox, thereby contaminating the oil. This oil circulates through the main components, the torque converter, gearbox and valve body, damaging them in the process. Our staff are highly trained to recondition all of these components and our prices are usually quoted for a fully remanufactured/fully guaranteed rebuild or exchange, inclusive of oil and labour.

Torque Converter

This allows the gearbox to remain stationary while the engine is running. One could say that the torque converter disconnects the engines torque output from the transmissions input. When the driver pushes the throttle, the oil pressure in the torque converter builds up. The centrifugal force activates clutches inside the converter thereby reconnecting engine and gearbox.

Mechanical Box

The mechanical side of an automatic gearbox is mainly made up of clutch plates, friction plates, drums and planetary gears. This is all controlled by an ECU (computer) and what is called a valve body, which is the 3rd part of an automatic gearbox.

Valve Body

The valve body is made up of tiny veins through which oil gets pushed by solenoids, thereby activating and deactivating the relevant clutch packs (gears). The valve body receives its instructions from a computer which calculates the required gear according to variables such as speed, throttle position, resistance (weight/load, and so on.
