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 GM Vans Get Transmission Updates


2020 GM Vans Get Transmission Updates

Recently, GM has announced that 2 of its 2020 models, namely Chevrolet Express and GMC Savana, will receive some upgrades of their transmission systems. It is claimed that the 8-speed automatics installed in both vans will be equipped with a fresh torque converters and absorbing mechanism. This measure is applied to models in which the powertrain includes the abovementioned gearbox paired with the Duramax engine.

GM engineers argue that both improvements ensure several advantages such as a quieter and more stable operation as well as enhanced durability. Output characteristics of the engine paired with the 8-speed shifting unit are rated at 180 hp at 3,400 RPM and 500 Nm at 2,000 RPM. Starting from 2020 model year, both vans will be sold on the automobile market in 3 variants, including Cargo, Passenger, and Cutaway. Each variant has its design features attributed to their applications.

At the same time, the powertrain range for the 2020 GM van models is the same as in the last year line, namely:



It should be noted that both vans are offered in all powertrain variants, with only one specific exception: the Duramax LWN engine is installed in Cargo and Passenger variants, but not in the Cutaway variant.
