A car transmission is the intricate nexus of gears and mechanisms that orchestrates the transfer of power from the engine to the wheels. Divided into manual and automatic types, transmissions manage torque and speed, crucially shaping a vehicle's performance and efficiency. Manual transmissions engage drivers with tactile gear shifts, offering control over acceleration and engine revs. Conversely, automatic transmissions optimize convenience by autonomously selecting gears based on speed and load. Both types synchronize the engine's power output with the wheels' rotational speed, ensuring smooth acceleration and maintaining fuel economy, making the transmission a cornerstone of automotive engineering.
