Probably every transmission repair specialist was keen on LEGO constructions or at least enjoyed making some minor things with their hands. Here's the game taken to a new level of creativity!

Modern auto industry is full of sophisticated drivetrain technologies which are supposed to make your driving experience even more pleasant and trouble-free. Despite a great abundance of sophisticated technical solutions, it is highly likely that very few people know a transmission solution operating like a manual CVT.

Over recent years engineers developed a lot of gear shifting solutions for different car brands, which may seem a bit unusual for oldtime drivers. In this article we will review the most peculiar gear stick technologies and provide video materials related to these technologies.

Only few people know about transmission concepts which were popular 70-90 years ago. For men of today, these gearboxes may seem very unusual and weird, but even now some gearboxes that date back to those years are quite competitive in comparison with modern transmissions.

Nowadays Extroid CVTs are commonly known as “toroidal” due to the fact that the working surface of driving and driven discs in this transmission has the form of a torus. Extroid CVT is not a V-belt transmission, but a friction drive CVT.

Allison Transmission Attaches Great Hopes to Natural Gas Technologies


Allison Transmission Attaches Great Hopes to Natural Gas Technologies

Last month, Allison Transmission took part in the Assembly, where Trond Johansen, company’s representative in Spain, shared his visions on prospects of natural gas to become the leading fuel option for heavy trucks and Allison automatics as an ideal supplement to natural gas engines.


Allison is quite enthusiastic about promoting natural gas as more environment-friendly alternative to conventional fuels. Therefore, the company plans to enhance the cooperation with Gasnam, the association focused on fostering the use of natural gas and renewable gas in land-based and maritime mobility in the Iberian Peninsula.


Allison designs and produces automatic gear shifting solutions that can be easily paired with compressed natural gas (CNG) and liquefied natural gas (LNG) engines. It has been proven in practice that Allison products improve the operating qualities of this non-conventional fuel and enhance efficiency of its performance on different types of vehicles. During his speech, Mr. Johansen also gave insights into benefits of Allison products in comparison to manual and automated manual gearboxes.

Currently, natural gas is the most promising option for heavy trucks, despite the fact that many automakers heavily invest in the electrification technologies. But the E-mobility initiative still has a long way to go in many aspects, while natural fuel is the only proven solution that will allow heavy-duty transport to cut CO2 emissions by 30% in 11 years.


Heavy vehicle powered by natural fuel are more productive because of higher effectiveness and better operational characteristics ensured by Allison’s automatics. Allison products allow truck drivers to speed up faster if compared to other gearboxes. Moreover, FuelSense, Allison’s latest fuel-saving software, not only facilitates lowering CO2 emissions, but also greatly cuts expenditures. Moreover, Allison technologies reduce the noise pollution level on the road by 50%-90% in contrast to diesel vehicles.

Allison will take part in the upcoming Gasnam Congress on April 10 and 11, where the company will have a chance to share more benefits of its products and explain why natural fuel engines and Allison automatics are the ideal match.
