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.

Ricardo Provides DCT Transmission Software for CEVT

Ricardo, a British-based engineering company, has recently taken an obligation to manufacture and supply transmission control software for a 7-speed DCT unit for CEVT, a Swedish-based innovation center specialized in mobility technologies for the Geely Group brands. It is planned that the new software will find application in a 2020 compact luxury crossover.


According to Ricardo, the software has been created on the basis of a ‘systemized track’ approach, in which the vehicle level specifications helped to specify the software of the gearbox control unit. Moreover, it is said that the software complies with the industry standard ‘A-Spice Level 2’. This included thorough testing at different levels, and providing complete traceability between the specification of each vehicle-level requirement, testing procedures and results.



Moreover, it is alleged that the new software also corresponds to the international standard of functional safety to provide in-built monitoring feature. Thus, in case of any software/hardware failure, the maximum operational availability of the gearbox will be maintained, while also taking into account its safe operation.


The process of software development for automobiles demands a well-thought and systemic approach to guarantee the necessary level of operational efficiency, fault-tolerance and safety, while also ensuring the required level of flexibility. Ricardo has already made a significant progress in this direction, but cannot afford to become complacent, as the software requirements become more complicated with rapid development of electric and hybrid vehicles.

CEVT has highest regard for professionalism of its English colleagues, as Ricardo always timely provided the necessary software releases for testing. Therefore, it became possible to fix all critical faults before the production launch.
