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.

Audi Recalls R8 Models due to Transmission Issue


Audi Recalls R8 Models due to Transmission Issue

Audi has recently reported about the recall of 1,916 R8 Coupe and Spyder models to eliminate a possible flame formation issue. Due to faults in the transmission ventilation hose, it is likely that transmission oil can drip out and get on the warmed-up engine, eventually leading to a flame development.

The Audi R8 was designed for high speeds. This supercar has a lower price than analogs produced by other car brands. No wonder that admirers of high speeds want to make the most out of the Audi R8 speed capacities. But owners of the abovementioned models should bear in mind that leakages of highly inflammable transmission oil may lead to road accidents.


The carmaker informed in its recall related documents that there are some “fast speed” and “maneuvering” cases when transmission oil seeps out the vent hose. Practically, it is most likely to happen when Audi R8 drivers compete at race tracks, and smoke generation probably will be noticeable long before the risk of fire. Anyway, the company expressed the readiness to fix the defect for free in all already purchased cars or check for transmission issues.

The problem emerged after several fire accidents which happened with Audi R8 sportcars at racing tracks. This prompted an internal investigation and helped to detect the source of malfunction. The recall will include R8 Coupe and Spyder models manufactured in 2017-18. Moreover, Audi launched a hotline for additional consultations.


Owners of the abovementioned models have to bring their cars back to their dealership centre to eliminate the problem. Specialists will replace the existing vent hose with a new double vent hose. That should be a perfect solution, and this service along with spare parts is reported to be absolutely free of charge. Audi will begin informing car owners on October 31. Unsold cars will also be inspected and repaired if needed.

Earlier it became known that, by a court decision, Audi must pay 800 million euros fine for being involved in the Dieselgate scandal.
