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.

2020 GMC Acadia Gets a New Gear Shifting Mechanism


2020 GMC Acadia Gets a New Gear Shifting Mechanism

As new car models are equipped with more and more advanced electronics, carmakers find new ways to add more free space in the driver’s cabin. The new digital push-button gear shifting mechanism in the upgraded 2020 Acadia is a vivid example of this trend , since this solution was designed to take the place of the conventional gear shifting mechanism implemented on the 2017-2019 Acadia, thus making more free space in the front row.




GM’s new product opens a fresh approach to controlling the 2020 Acadia’s 9-speed automatic gearbox by means of easy-to-understand mechanisms. In addition to the sophisticated gear shifting interface, this solution allowed GM engineers to save space in the area of the center console.




In particular, the bin located at the front of the center console of the updated Acadia has much larger dimensions in comparison with its preceding models. Drivers will be also pleasantly surprised to find convenient storage area between the car’s floor and its center console, where they will be able to put their personal items (a purse or wallet).




Moreover, the new gear shifting solution also helped engineers to optimize the positioning of the front cup holders (from the initial longitudinal arrangement to transversal). The new solution does not prevent a driver from freely taking or putting a beverage. But for some people accustomed to putting a hand on the lever while driving, it may initially feel uncomfortable till they get used to the new gear shifting mechanism.




In addition to space saving advantages, the new solution also ensures smoother and more accurate performance capacity, as well as a reduction of overall noise and vibration levels. This gear-shifting principle also found application in Buick LaCrosse, Chevrolet Bolt, and numerous Cadillac models. But all these models are equipped with a “joystick-style” shifter, unlike the push-button solution implemented in the latest Acadia. GMC’s push-button EPS interface was firstly implemented on the 2018 GMC Terrain.
