Everyone knows about the terms of gearbox and transmission, but not many are aware of the differences between the numerous categories of gearboxes available today. Any car fueled by an inner combustion engine demands a transmission.
But transmission is something that monitors the engine’s speed based on the power needed. In this article, we have discussed the major types of transmissions, with their pros and cons, so that you can learn basic information about them.
Manual Transmission
This is the oldest and simplest transmission. The gearbox is controlled by the driver’s foot to link the input shaft usage with the engine’s rotational energy. It displays a friction clutch as the main technique.
A gear-selector fork and Syncro positioned to the shifter and controlled by the driver’s right hand is also utilized in some countries. This transmission has been called different names over the years – stick shift, 6-speed, standard, 5, 4, and 3.
Latest drivers are unaware how to use the manual, and it’s becoming an extinct species. Plus, very few models feature a row-it-yourself gearbox these days.
But irrespective of bleak appearance, there are perks of manual transmission, which is absent in poise alternatives. For instance, it’s simpler and cheaper to replace. No matter how much other transmissions are hyped up, the manual is always more efficient.

Automatic Transmission
This modern configuration has been active since 1940, and is a part of all current vehicles. Only an accelerator and brake are employed, while the clutch pedal is skipped. The latest automatic transmissions are more difficult to operate as compared to the above option.
It first came with 2- and 3- speed arrangements, but the latest transmissions contain 8- and 10- units. The torque converter serves as a substitution for the clutch pedal in the manual gearbox. Gears are switched smoothly without interacting. Plus, this transmission offers a better driving experience, utility, and efficiency.
This gearbox has refined shifting and is way quicker than the manual. And this is the primary reason why it’s dominant in the market.
Automatic transmission is indispensable for particular car categories, like pick-up trucks and SUVs. The modern gearboxes also include a manual mode through which it can be functioned by choosing the desired gear.

Continuously Variable Transmission
Regarding driving convenience, this gearbox resembles the automatic transmission. However, it’s operation is completely different, but easier than automatic. There are no gears, as it relies on an arrangement of pulleys and belts to produce countless ratios.
Furthermore, the vehicle’s computer influences the modification of the pulleys to create an ideal balance for any type of driving. CVT excels in fuel efficiency as it provides greater MPGs compared to all other gearboxes.
Due to a simple operation, their repairs aren’t expensive, and are reliable. The only flaw that is observed in CVT is the driving pleasure. Driving enthusiasts don’t have fun driving a CVT due to zero gearshifts.
Sequence Manual Transmission
This gearbox is rarely seen in models, but race car drivers prefer it. The sophisticated technique pairs the control and feel of a manual gearbox with the accuracy and speed of an automated message. In simple words, it’s manufactured to live up to the racetrack demands.
But a clutch is still available – only for choosing the first gear and to start the car. Afterward, paddle shifters and gear levers are employed to change gears. Plus, it enables the concentration on driving and the gears are shifted smoothly without having to squeeze the clutch each time.
Sequence manual gearbox comes with a high price tag. Another downside is that there are no skip gears.
Dual-Clutch Transmission
This gearbox is a cross between the manual and automatic transmissions. A semi-autonomous system showcases a similar construction to a standard gearbox. However, it shifts gears with the help of actuators and pneumatics.
In the DCT, there are two clutches for even and odd gears, enabling fast shifts. Plus, this gearbox is generally completely automatic, but the steering wheel paddles can be shifted manually.
Both DCT and semi-autonomous gearboxes offer outstanding extremely fast gear shifts and exceptional performance that can not be rivaled with a manual transmission.
DCT is only found in upscale sports cars and racecars, which means they are very expensive. This disadvantage is intensified with the sheer complexity. You can expect frequent and expensive repairs.
