The Automatic Vehicle

The main difference between automatic and manual reach beyond just the presence or absence of a clutch and gear shifting. The biggest difference is that a manual transmission uses different sets of gears to achieve various gear ratios while an automatic version uses the same set of gears. An automatic transmission is made up of many parts, including:

• The torque converter is a type of fluid coupling that allows the engine to remain running and the transmission to stay in gear while stationary. It provides variable amounts of torque multiplication at low engine speeds.
• The pump pressurizes fluid which the transmission needs to operate.
• The planetary gearset allows for multiple gear ratios.
• Clutches and bands hold certain members of the gearset still while the others rotate to produce different ratios and reductions.
• The valve body and hydraulic and lubricating oil also help the vehicle run at full efficiency and productivity.
