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.

Donaldson Presents New Powertrain Vents


Donaldson Presents New Powertrain Vents

Donaldson Company, a major supplier of filtering solutions, has recently released new protective vents designed to save automotive powertrains from contaminating agents and pressure loads.


The company now offers 4 new products – the Screw-Fit and 3 Hose-Fit Powertrain Vents – that ensure optimized assembly and enhanced vent service life for vehicles working under severe conditions. Designs of these vents are notable for presence of unique oil-coalescing pre-filters, ensuring airflow maintenance. Powertrain vents (PV) are extremely helpful when it comes to protecting a car’s gearbox, axles and other elements from negative impacts and control pressure alterations that can affect some housing elements.

PVs play an important role in operating characteristics and durability of cars, but standard vent hoses have been quite complex to install and they usually get clogged with lubricants. Donaldson’s space-saving solutions can be easily incorporated into any powertrain unit, and their special pre-filters help them to operate longer and perform more efficiently than any analogs currently available on the automotive market. Moreover, new solutions are more compact than standard analogs.


To solve the most challenging issue related to car venting – an accumulation of lubricating film that decreases venting airflow – company’s engineers equipped new vents with a coalescing pre-filter. By effectively filtering oil particles, Donaldson vents ensure better operating characteristics and prolonged operating life. The new offerings will compliment Donaldson’s solid auto portfolio, which includes a wide range of venting products for other car units.


The IVS business unit of Donaldson works on venting technologies to keep the main automotive components safe from debris, lubricants and other liquids, at the same time ensuring pressure balancing in and around components. Thanks to the high level of professionalism and top-quality products, the company managed to earn a great reputation in numerous industries.
