Automatic gearbox

Most automatic gearboxes have three forward speeds, and use two sets of epicyclic gears. The locking sequences of the epicyclic gear train are achieved by hydraulic pressure operating brake bands or multi-plate clutches.

The bands are tightened round the ring gear to prevent it turning, and the clutches are used to lock the sun gear and planets. Many automatic gearboxes enable you to make manual gear changes, either through the gear selector lever or paddles mounted on the steering column.

This uses hydraulic fluid to transmit drive between the engine and gearbox. DSG dual-clutch gearbox. Two independent gearboxes are connected under load to the engine in turn, depending on the current gear, via two drive shafts. An output shaft assigned to each gearbox applies the torque to the driven.

When you get into a car with an automatic gearbox, it should have been left in ‘park’. Put your right foot on the left-hand pedal (the brake) and push down, start the car using the key or start button, and (with your foot still on the brake), move the shifter to ‘D’ (if you want to drive forward) or ‘R’ (if you wish to reverse).

An automatic transmission, also called auto, self-shifting transmission, n-speed automatic (where n represents its number of forward gear ratios), or AT, is a type of motor vehicle transmission that automatically changes the gear ratio as the vehicle moves, meaning that the driver does not have to shift the gears manually. The key difference between a manual and an automatic transmission is that the manual transmission locks and unlocks different sets of gears to the output shaft to achieve the various gear ratios, while in an automatic transmission, the same set of gears produces all of the different gear ratios.

The planetary gearset is the device that makes this possible in an automatic transmission.

A semi- automatic transmission (also known as a clutchless manual, auto-manual, semi-manual, or paddle-shift gearbox in motorsports), is an automobile transmission that combines mechanisms of a manual and automatic transmission. Semi- automatic transmission refers to a conventional manual transmission with an automatic clutch.

They facilitate gear shifts for the driver by operating the clutch system automatically, while still requiring the driver to manually shift gears. The CVT gearbox, and variations thereof, has been around since the dawn of the motorcar, but it was the introduction of the Variomatic gearbox by Dutch car maker DAF.

It automatically disconnects the engine from the road wheels while changing gear. By far the most common cause of trouble with an automatic gearbox is incorrect fluid level (see sideline, opposite).

An automatic transmission usually has more than one planetary gear set. Automatic cars don’t have a clutch pedal or a gear stick. They work together to create multiple gear ratios. Parkers has a huge range of approved-used automatic cars for sale across the UK.

All the cars on sale have been checked and tested by approved dealers, many come with a warranty, giving you peace of mind when searching for automatic cars in the classified ads. Grinding or shaking sensation in gear.
