Is Sequential Transmission Better Than DCT?

Is Sequential Transmission Better Than DCT? When it comes to car transmissions for sale in the market, sequential and dual-clutch transmissions are making strides. They both ensure quick and smooth shifting between gears. But their mechanism is different from each other.

So, how will you ensure which one is better for you than the other? In this blog, we’ll compare the pros of Sequential transmissions and DCTs to highlight which one is better so you can buy a quality transmission for your ride.

Sequential Transmission The sequential transmission’s mechanism is similar to the regular manual transmissions. They both allow the drivers to upshift and downshift rapidly.

However, the gears must be changed in the pre-set order.

You cannot move directly from one gear to the other without following the order of the preceding or the following gear. For example, if you want to shift from the 6th to the 3rd gear on a manual transmission, you can go directly from the 6th position to the 3rd position. But on a sequential transmission, you will have to go through the whole sequence from 6th to 5th to 4th, and then to 3rd.

Benefits of Sequential Transmissions Sequential transmissions are costly, but they offer worthy benefits like the following.

•

Super-quick gear shifts: Sequential transmission enables you to shift gears quickly, which regular manual transmission can’t make possible.

Manual transmissions still need a few seconds to change the gear, but sequential ones make it super quick.

•

Lightweight: Since sequential transmissions have fewer components, they are lighter than other transmissions, especially dual clutch. On the other hand, DCT has the highest number of components. Reducing weight improves performance on the racetrack.

Dual Clutch Transmission Dual-clutch transmissions (DCT) work on a mechanism that’s a blend of manual and automatic transmissions. But DCTs are not automatics but rather closer to a manual transmission.

Dual clutch transmission, as the name suggests, uses two clutches. These clutches are controlled electronically and not with a clutch pedal. DCTS is programmed to engage & disengage automatically as needed without the need for the driver to intervene.

Benefits of Dual Clutch Transmissions Dual-clutch transmissions are found on many performance cars and several everyday cars due to the following benefits they offer.

•

Smooth Shifting: DCTs are the definition of smooth gear shifts as they hardly take more than a few milliseconds to change gears. Drivers don’t experience any shift shocks, and the accelerations are smooth & continuous.

•

Improved Efficiency: Fuel efficiency is a must-have of auto parts nowadays, and DCTs stand true to that. DCTs are more fuel-efficient than sequential transmissions. They ensure a better acceleration experience and improved fuel efficiency.

Conclusion Both sequential transmission and DCT enable shifting gears without a clutch pedal. Both are designed for high-performing cars as they considerably saved precious milliseconds during shifting.

However, dual-clutch transmissions have found their way to our everyday driving cars over the past few years, while the sequential transmission is better suited for racetracks.

So, that answer which is better among them. If you’re looking for a car transmission for sale for your city car, DCT is a clear choice.
