There is no engine component more complex and essential than a car’s transmission. Transmissions are responsible for shifting gears (automatically or manually) to dynamically change the speed-torque ratio in order to deliver power to the wheels in an efficient manner based on the speed of the vehicle. The reason for this is that engines output a high rotational speed which cannot be used for low speeds or starting. Using gear ratios, a transmission reduces the rotational speed and increases the torque (or “power” to the wheels) in the process.

Vehicles are usually described as 5 or 6 “speed” meaning then have that many gear ratios to allow the vehicle to travel at the full range of speeds required and to make use of the engine’s output power as efficiently as possible. Due to their complexity, constant use and function within a vehicle’s operation, transmissions experience a lot of wear and tear. Add to this the fact that many owner’s forget to check and change the fluid on a regular basis and it’s easy to understand why so many people have transmission problems.
