TVS Motors has patented a new type of transmission for motorcycles. Christened SMT (semi-automated manual transmission), this gearbox is an evolution of the clutchless gearbox that the company had first used in the TVS Jive, back in 2010.

This new gearbox will employ buttons on the switchgear to allow the rider to change gears. Whenever these buttons are triggered, an electric motor will take care of changing the gear according to the rider’s preference. TVS says that this SMT gearbox can also be used for three-wheelers. Since the principle behind the operation of the gearbox is the same, there won’t be a drop in fuel efficiency. Honda uses a similar mechanism for its litre-class range including the VFR1200 and the Africa Twin, though the gearbox in question is a completely automatic transmission unlike the one patented by TVS.

While the Jive’s transmission was quite revolutionary, this mechanism had a few issues. The effort required to engage a gear was larger than on a conventional gearbox. Besides, even a slight pressure on the gear lever activated the clutch, leading to unexpected behaviour of the powertrain and an increase in fuel consumption. With this new SMT gearbox, TVS will aim to retain the convenience while getting rid of the niggles.

recent years AMT gearbox has gained immense popularity, and its use in entry level cars is more prevalent than ever before. It offers an unbeatable combination of affordability and convenience. Not only that, the fuel efficiency that it has to offer is in fact more than what you would get with a manual gearboxes. They are also not expensive to maintain as some of the other automatic gearbox technologies. So, how does it work? The article answers some basic questions related to the AMT transmission.

What is an AMT transmission?

At the heart of the AMT transmission is a manual gearbox, hence the name – Automated Manual transmission. It is a two pedal technology just like all other automatic transmissions, and uses actuators for clutch and gearshift operations. Actuators are either electro-mechanical or electro-hydraulic type.

Note that there is a clutch, but no clutch pedal, so in the background the clutch and shifts are operated by actuators. All this is precisely controlled by the TCU (Transmission Control Unit).

Which cars offer the AMT transmission?

Maruti Alto K10, Tata Nano, Maruti Swift Dzire, Renault Duster, Tata Zest, Mahindra TUV300 are a few other cars that offer AMT transmission.

What are the modes of operation available in an AMT gearbox?

Most AMT gearboxes offer two modes of operation – Semi automatic & fully automatic. In case of fully automatic mode, the car drives like an automatic car and gear change takes place in accordance with your input at the accelerator / brake pedal. While the semi automatic mode has a provision for driver input and he can change the gears by pushing the gear lever forward or back. However, unlike a manual, there’s no need of clutch.

Are there any other differences between AMT and traditional automatic gearbox?

A traditional automatic offers ‘Creep’ function which enables the car to move forward as soon you take your foot off the brake pedal. Until recently the AMTs offered by different car companies did not offer the ‘Creep’ function and therefore, you required to use the accelerator pedal after releasing the brake pedal.

The new AMT systems developed by companies like Ricardo for TUV300 offer the creep function. Another car that offers the creep function includes Tata Nano. Cars from Maruti like Celerio and Alto K10 does not offer this feature. The Tata Zest is another car that skips the Creep functionality.
