Gearboxes (Automatics)


Has your Automatic vehicle got a gearbox problem?

Slipping, flaring, dragging or labouring? Has it got a loss of drive? Does it need to have the gearbox oil renew or replaced? Pentagon Motorist Centre in Chatham Medway can diagnose a faulty gearbox

Automatic Gearbox:

An automatic gearbox, self-shifting gearbox or A/T is a type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually.
The most popular form found in vehicles is the hydraulic automatic transmission. This system uses a fluid in place of a friction clutch and changes gear by locking and unlocking a system of planetary gears.

In contrast to conventional automatic transmissions, continuously variable transmission CVT, uses a belt or other torque transmission scheme to allow an “infinite” number of gear ratios instead of a fixed number of gear ratios.

A semi-automatic has a clutch like a manual transmission, but the clutch is controlled through electro hydraulic means. Manumatics such as Tiptronic often use paddle shifters that change gear manually for the driver without having to move the gear stick.

Common Faults:

The most common problem with automatic gearboxes is when gear changes are labouring or dragging. If there is a loss of drive some people describe this as slipping or flaring and the most common reason is due to low oil.

A semi-automatic gearbox still has a clutch so the most common problem when these gearboxes become faulty is due to the clutch being worn out and needing to be renewed. Many people are unaware that holding a semi-automatic in gear on a hill is slipping the clutch and is causing undue wear.
