Car Mechanics Automobile Transmissions Diagram
Introduction
A car’s transmission is a complex system of gears that allows the engine to deliver power to the wheels. The most common type of transmission is the manual transmission, which requires the driver to shift gears manually. Automatic transmissions, which shift gears automatically, are also popular. There are also a variety of other types of transmissions, such as continuously variable transmissions (CVTs) and dual-clutch transmissions (DCTs).
The diagram below shows a simplified view of a manual transmission. The engine is connected to the transmission through the clutch. The clutch allows the driver to disconnect the engine from the transmission, which is necessary when shifting gears. The transmission is connected to the wheels through the driveshaft. The driveshaft is a long, rotating shaft that transmits power from the transmission to the wheels.

How a Manual Transmission Works
When the driver shifts gears, they are moving the gearshift lever to engage different gears in the transmission. Each gear has a different ratio, which determines how much the engine’s power is multiplied. When the driver shifts into a lower gear, the engine’s power is multiplied more, which gives the car more torque. This is useful when driving in low-speed situations, such as when climbing hills or towing a trailer.
When the driver shifts into a higher gear, the engine’s power is multiplied less, which gives the car more speed. This is useful when driving in high-speed situations, such as when cruising on the highway.
Automatic Transmissions
Automatic transmissions are similar to manual transmissions, but they shift gears automatically. Automatic transmissions use a variety of sensors to determine when to shift gears. These sensors include the engine speed sensor, the transmission speed sensor, and the throttle position sensor.
The engine speed sensor measures the speed of the engine. The transmission speed sensor measures the speed of the transmission. The throttle position sensor measures the position of the accelerator pedal.
The transmission control unit (TCU) uses the information from these sensors to determine when to shift gears. The TCU is a computer that is located in the transmission. The TCU controls the transmission’s solenoids, which shift the gears.
Other Types of Transmissions
In addition to manual and automatic transmissions, there are also a variety of other types of transmissions. These include:
- Continuously variable transmissions (CVTs)
- Dual-clutch transmissions (DCTs)
- Automated manual transmissions (AMTs)
- Sequential manual transmissions (SMTs)
- Paddle-shift transmissions
CVTs are becoming increasingly popular because they offer a smooth, efficient driving experience. CVTs use a belt or chain to connect the engine to the transmission. The belt or chain can change its length, which allows the transmission to change gears without any interruption in power.
DCTs are similar to manual transmissions, but they use two clutches instead of one. This allows the transmission to shift gears very quickly and smoothly. DCTs are often used in high-performance cars.
AMTs are similar to automatic transmissions, but they use a manual clutch. This gives the driver more control over the car’s performance.
SMTs are similar to manual transmissions, but they use a sequential gearshift lever. This makes it easier for the driver to shift gears quickly and smoothly.
Paddle-shift transmissions are similar to manual transmissions, but they use paddles on the steering wheel to shift gears. This allows the driver to shift gears without taking their hands off the wheel.
Conclusion
Transmissions are an essential part of any car. They allow the engine to deliver power to the wheels, which makes it possible for the car to move. There are a variety of different types of transmissions available, each with its own advantages and disadvantages. The best type of transmission for a particular car depends on the car’s intended use.
