High Performance Car Transmissions

A transmission or gearbox is the system of gears that transmits mechanical power from the engine which ends at the wheels to produce higher torque/speeds.

The difference between Automatic Transmissions and Manual Gear boxes is that Automatic Transmissions change gear ratios automatically as the vehicle moves therefore not giving the driver control over when to shift gears, Where as the Manual Gearbox allows the driver to shift gears according to their needs whether it be high for high torque or high speeds.

Transmissions provide a major speed-power conversion known as gear reduction (in speed) to a higher torque by using gear sets. The cars transmission provides different speed-power ratios. Performance car transmissions must match the power output of the engine for the vehicle to perform at its peak and to reduce the risk of engine damage from over revving the engine.

All transmissions have different gear ratios and several gears to provide for high and low speed torque.

Low gears are used to give the car higher torque at low speeds and high gears increase the speed but have a lower torque therefore the more gears that the Transmission/Gearbox has the higher the speeds that can be gained. So by changing the gear ratios in the transmission/gearboxes you can maximize the power output and acceleration at any given speed. So you can now you can see the importance of the Transmission /Gearbox optimization has on high performance cars.
