                                                   CLUTCH

A clutch is two metal plates in the engine. When you press the clutch pedal down the plates come apart separating the engine from the drive wheels allowing you to change gear. Bringing the pedal back up re-engages the plates which in turn connect the engine to the drive wheels. As your car engine is constantly running, a clutch is needed to separate the engine from the drive wheels when you stop the car. Pressing the clutch down just before you stop does just this, otherwise the car would stall.

Transaxle Gearbox

In the automotive field, a transaxle is a major mechanical component that combines the functionality of the transmission, the differential, and associated components of the driven axle into one integrated assembly.

Synchroniser: it is a toothed ring between the gears of a manual transmission that helps bring the 2 sets of gears to the same speed so they mesh easily during a shift.

Circlip: A circlip (a combination of 'circle' and 'clip', and pronounced thus), also known as a C-Clip, snap ring or Jesus clip, is a type of fastener consisting of a semi-flexible metal ring with open ends which can be snapped into place, into a machined groove on a dowel pin or other part to permit rotation but to prevent lateral movement. There are two basic types: internal and external, referring to whether they are fitted into a bore or over a shaft. Circlips are often used to secure pinned connections.

Bell housing: is a colloquial/slang term for the portion of the transmission that covers the flywheel and the clutch or torque converter of the transmission on vehicles powered by internal combustion engines.

Torque converter: The torque converter normally takes the place of a mechanical clutch in a vehicle with an automatic transmission, allowing the load to be separated from the power source. It is usually located between the engine's flex plate and the transmission.
