Manual Transmission

The transmission or gearbox is one of the most important parts of the automobile, which helps in speed torque conversion and thus helps to run the car at different speeds. The transmission used in automobiles is generally divided in to different categories. They are manual transmissions, non synchronous transmissions, automatic transmissions and semi automatic transmissions.

First of all the manual transmission is also called as the manual gearbox. This type of transmission consists of the clutch which is operated by the driver and the gear shift. The clutch is for the purpose of regulating transfer of torque from the engine to transmission. The gear shift is used for selecting different gear ratio according to the speed of the vehicle. The manual transmission is further classified in to two types. They are sliding mesh and constant mesh transmissions.

The former type does not make use of synchronizer so the driver has to take entire control of matching the engine speed to the wheel speed and it is commonly used in the race cars and the some old heavy duty trucks. The latter type can comprise synchromesh systems for ease of use and it is extensively used. The manual transmission is very popular because of its performance and fuel efficiency.

The second type of transmissions is the non synchronous transmission. Here the transmission does not use the synchronizing mechanisms of any form. They are usually found in certain types of commercial and agricultural vehicles. This type is designed for the trained drivers who can understand and coordinate the gear shift in the correct timing and these transmissions can carry heavy loads.

In the automatic transmissions, the gearbox in the vehicle can itself change the gear ratios automatically based on the speeds. This is done by situating a torque converter in between the engine and transmission. Such transmissions help to alleviate the driver from manually changing the gear ratios. So the vehicles with automatic transmissions are very easy to drive. There are certain modes in the automatic transmissions and they are park mode, reverse mode and neural mode. Some of the applications of this type of transmissions are in drag racing and in turbocharged engines.

The final type of transmissions is the semi automatic transmissions and it is also called as automated manual transmission. Here processors, actuators and the electric sensors are used in order to implement the shift of gear ratios. But the shift of the gear ratio is controlled by the driver. This type of transmissions offers better driving experience than the other types. You can buy used transmissions for your car as a replacement. It is the best choice if you want the preferred transmissions for considerable prices.In used-transmissions.com, you can buy used manual transmissions and used auto transmissions.
