The clutch is a crucial part of the drivetrain of any automobile equipped with a manual transmission. It has two main functions: first is to connect and transmit power from…

The differential receives engine power from the driveshaft and splits it between two axle shafts, which drive the wheels on an axle. On a rear-wheel drive, there’s one differential on…

An automatic transmission uses fluid to lubricate its internal clutches, gears, and bearings. It incorporates a torque converter as a viscous coupling that uses transmission fluid to transfer engine power…

There are two types of slave cylinder. The most common kind is one that is basically a piston in a sleeve which is bolted to the side or top of…

The seal itself is rubber bonded to a metal casing, with a flanged lip that bears on the axle. It relies on a tiny amount of lubrication from the fluid…

The shift cable both pushes and pulls as it operates, so it’s a relatively rigid steel cable in a relatively stiff housing. On an automatic transmission, the shift cable connects…

CV axles are most commonly used on the front-wheel-drive vehicles to transfer engine power from the transaxle to the wheels. Some all-wheel-drive vehicles with independent rear suspensions also use CV…

In an ordinary automatic transmission, the gears are shifted by directing the pressurized transmission fluid to a variety of hydraulic clutches. On older designs, the fluid is directed by valves…

On a differential, the power input from a driveshaft begins with the pinion flange, which the driveshaft bolts to. The pinion flange is splined and bolted to the pinion gear,…
