In the Modern-day automotive world, How each of these differs from each other and which one to choose based on your specific needs, so with traffic getting worse and worse for the day in India most of us are opting for Automatic Transmissions Systems when we want to purchase a new car although these variants come at a premium than a manual transmission, so let’s try to see what are the various Automatic Transmissions Systems that are available in Indian cars today. Here is the list of Automatic Transmissions Systems:-
- Torque Converter or Conventional Automatic Transmission (AT)
- Automated Manual Transmission (AMT)
- Continuously Variable Transmission (CVT)
- Dual Clutch Transmission (DCT)
Torque Converter or Conventional Automatic Transmission (AT)
The conventional automatic transmission remains the most popular most common form of automatic transmissions globally torque converters have been around for a long time now. The gearbox torque converters are made up of three main components
These three components lock and unlock with the help of multiple clutches and maintain predetermined gear ratios.
however conventional ATS can sometimes take away a fair bit of power resulting in power losses in the drivetrain and provides poor fuel economy compared to regular manual transmission the positives of a conventional automatic transmission are smooth gearshifts and reliability in terms of negatives fuel efficiency is lower compared to other types of gearboxes.
Automated Manual Transmission (AMT)
Automated Manual Transmission is one of the simplest implementations of an AT and is also the most cost effective, however with advancement in technology the AMT gearbox has made a comeback in emerging markets like India the AMT is a regular manual gearbox but with the addition of an electro-hydraulic system.
Which comprises of an electronic control unit and a hydraulic system this system which is also known as the Transmission Control Unit TCU. AMTs also offer a manual shift mode where the driver can change gears by using then gear shifter without having to use clutch due to the cost effectiveness it is mostly found in budget cars like the Maruti Suzuki Wagoner, Renault kwid and so on.
We can see that AMTs are the most cost effective transmission compared to its counterparts AMTs are also known to deliver high fuel efficiency something at the level of manual transmissions in terms of downsides AMTs are known to have slower gear shifts and they are also not smooth and produce a gear shift sound that you often hear in manual transmission moving on.
Continuously Variable Transmission (CVT)
CVT a Continuously Variable Transmission CVT s are one of the most defined automatic transmissions the CVT is use steel pulleys and the belt that can generate infinite Q ratios this means that there really are no gear changes are such leading to smooth seamless power delivery this type of transmission is very quiet – and is widely used in scooters in India.
However CVTs can feel a bit elastic when you drive them especially when you notice what is called a rubber band effect premium cars like the Hyundai i20, Maruti Baleno use these types of transmissions CVT can also get paddle shifters to give them a sporty appeal in India Honda cars like the Jazz City and civic offer paddle shifters with a CVT.
The best fuel economy among all automatic transmissions they also have smooth operation in stops at traffic situations in terms of cons Seabury suffer from a rubber band effect when Hard are also known to have slow acceleration
Dual Clutch Transmission (DCT)
A Dual Clutch Transmission or DCT uses two separate shafts with their own clutches for gear shifts one shaft for odd-numbered gears and the other one for even-numbered gears this type of automatic transmission provides quick shifts and delivers good fuel efficiency.
However, since the technology involved in a system is fairly complex and consists of a number of electronic components the costs associated with manufacturing a DCT.
It is relatively higher which is also the main reason for its lower level of adoption maintenance costs are another area of concern for these cities cars like the Volkswagen Polo, Amiyo, Skoda Rapid, Skoda Octavia are all available with dual-clutch transmissions.
Think to note Volkswagen has its own variant of the DCT, which it calls the DSG or direct shift gearbox in terms of positives these cities are known to have lightning-quick upshifts and downshifts they also have great performance.
Fuel efficiency but in terms of negatives these cities have higher manufacturing and maintenance costs and they are heavier than other transmission options so which one should you choose given an option well if you’re looking for a low-cost gearbox.
Also, cheap to maintain you will go for an AMT fuel efficiency on a MTS are at par with the manual counterparts and is yet another reason why you may go for an AMD that said if you’re looking for the best possible fuel efficiency then the CVT has got to be a pig not many manufacturers offer a CVT these days so that could be a concern.
When you’re looking for an ex car and if performance is of utmost importance to you then you’ve got to choose a DCT transmission model these cities are quick to shift and have minimal to no loss in power and torque and do not compromise on fuel efficiency.
