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.

Situation Around To-Be-Closed GM Plants Stays Unclear


Situation Around To-Be-Closed GM Plants Stays Unclear

The situation around GM plans to close several plants, including 2 transmission plants, brings up more questions than answers. Recently, it has transpired that the United Auto Workers is filing a lawsuit against GM because of the carmaker's intentions to shut down 3 U.S. plants before expiration of the existing employment agreement.




The union is determined to stand up for the rights of plants involved in the suit to continue to work at least until the existing agreement between the UAW and GM expires in early Autumn. GM, in turn, wants to close the plants in the near future.

It should be reminded that at the end of November 2018 GM reported its plan to close 5 production facilities in North America and put out of work approximately 14 thousand specialists by the end of 2019. This restructuring measure was caused by rising costs and slower car sales. However, this step caused dissatisfaction among public officials, including the US president.


That’s how it all started…..


The list of affected plants includes gearbox manufacturing facilities in Warren (Michigan) and in Baltimore. The Baltimore plant, producing of Allison 1000 gearboxes for GM trucks, should be closed by April 1, 2019. Unless GM is ready to purchase the gearboxes directly from Allison or open a new production facility, it could mean that a new gearbox will be installed on T1 2500/3500 trucks.


Warren Transmission is supposed to stay in operation until August 1, 2019 , when it will stop manufacturing 6-speed gearboxes for the Chevrolet Volt. Gearboxes from Warren found application not only in now discontinued XTS, Impala, and Volt, but also in the Acadia and Malibu models that are currently produced. Without the supply of 6-speed gearboxes, it is expected that the Acadia model will be equipped with the new 9-speed gearbox designed by GM jointly with Ford. Despite the court case, it is expected that a final decision on the fate of GM plants will be made during talks between GM and the UAW planned for this summer.
