Manual and Automatic Transmission Components and Their Functions

The transmission is one of the key components in a vehicle's drivetrain, whether it's a car, motorcycle, or other vehicles. The function of transmission is to convert the engine's power into motion that can be used to drive the wheels.

In the automotive sector, there are two main types of transmissions commonly used: manual transmission and automatic transmission. Both have different components and unique ways of working.

Let’s dive deeper into the components of each type of transmission!

Manual Transmission Components

A manual transmission is a system that requires the driver to manually change gears using the gear lever. Some key components of a manual transmission include:

1. Transmission Gears

These gears are responsible for converting the engine’s power into torque that suits the vehicle’s needs. The driver can select the appropriate gear depending on the terrain and desired speed.

2. Input Shaft

This component is the axis connected to the clutch and is used to rotate the gears in the gearbox.

3. Shift Fork

The shift fork plays a role in moving the gears according to the driver's needs.

4. Synchronizer Gears

Synchronizer gears prevent problems when two gears are not in the same position. Additionally, this component makes it easier for the driver to manage gear speeds.

5. Gear Lever

The gear lever is a distinctive feature of manual transmissions which allowing the driver to easily shift gears.

6. Transmission Housing

The transmission housing serves to protect all the transmission components and acts as a reservoir for the transmission oil.

7. Input Shaft

This component transmits power from the clutch to the gears and functions as the input shaft.

8. Output Shaft

The output shaft holds the gears in place and helps transfer torque to the final gear set.

9. Reverse Gear

The reverse gear in a manual transmission allows the vehicle to move in reverse by reversing the rotation in the output shaft.

10. Speedometer Gear

The speedometer gear works by moving a cable that measures the vehicle’s speed.

Automatic Transmission Components

Unlike manual transmission, an automatic transmission shifts gears automatically without requiring the driver's intervention. Below are some key components of an automatic transmission:

1. Brake

The brake is used to obtain the vehicle's gear ratio by utilizing hydraulic pressure.

2. Automatic Transmission Fluid (ATF)

This fluid aids in the shifting process and helps cool the various moving components.

3. Torque Converter

The torque converter increases the engine’s torque and drives the oil pump.

4. One-Way Clutch

The one-way clutch helps link the torque and disengage the connection between the torque converter and the planetary gear.

5. Hydraulic Control System

This system controls the automatic operation of the transmission’s clutch and brake.

6. Shifting Control

The shifting control changes the engine load into hydraulic pressure, which then flows to various components.

7. Acceleration Pedal

The acceleration pedal connects the throttle valve to the cable, adjusting the acceleration pressure according to the driver's needs.
