Engine transmission- An overview of types of transmission, advantages & disadvantages.

Audible

Transmission refers simply to the gearbox that uses gears and gear trains to provide speed and torque conversions from a rotating power source to another device. There are two types of transmission mainly Manual transmission and Automatic transmission.


A manual transmission, also known as a stick shift or manual gearbox, is a type of vehicle transmission that requires the driver to manually shift gears.



Advantages of manual transmission:

•Driving with manual transmission gives you more control of the vehicle because you shift the gears. It will be easier to slow down or stop when you drive a manual vehicle.

•Manual transmission requires less maintenance and is cheaper to repair.

•Manual vehicles are more fuel-efficient than their automatic counterparts.

•Manual vehicles are less likely to be stolen because they are not as popular as automatic vehicles.


Disadvantages of manual transmission:

•Driving a manual transmission vehicle can present more safety challenges because it requires the driver to take one hand off of the wheel.

•The driver of a manual transmission vehicle has to constantly work three different foot pedals: the clutch, the brake, and the accelerator.

•It is much more difficult to learn how to drive a manual transmission vehicle.

•It is difficult to sell a manual transmission vehicle.


Automatic Transmission:-          

An automatic transmission, also called auto, self-shifting transmission, , is a type of transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to pressing the clutch and shift gears manually. Like other transmission systems on vehicles, it allows an internal combustion engine, best suited to run at a relatively high rotational speed, to provide a range of speed and torque outputs necessary for vehicular travel.


Here are the main advantages of an automatic transmission:

•Vehicles with automatic transmission are a lot easier to use because the transmission will do the gear shifting for you.

•Automatic vehicles allow you to keep both your hands on the steering wheel for added safety in driving.

•Driving an automatic vehicle facilitates greater comfort for the driver because his feet have to work just two pedals – the accelerator and the brake.


An automatic transmission presents disadvantages, too, including the following:

•Automatic vehicles are more expensive than manual transmission vehicles. They are also more expensive to maintain and repair.

•An automatic vehicle depends on the torque convertor to switch gears, making it less fuel-efficient.
