1. Housing: As the core structure of the transmission, it houses all internal components and securely mounts to the car or truck.
2. Input Shaft: Transmits power from the engine to the transmission.
3. Output Shaft: Transfers the power generated by the transmission to the drive wheels.
4. Transmission Assembly: Consists of gears and clutches, adjusting the transmission ratio between the input and output shafts to achieve different vehicle speeds.
5. Lubrication System: Lubricates and cools the moving parts within the transmission, reducing wear and providing cooling.
6. Control System: Controls such as levers and pedals operate the clutch and shift mechanism.
7. Filter: Removes foreign matter from the transmission oil, protecting the transmission's internal components.
8. Oil Pump: Provides essential lubrication to the transmission's moving components.
