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.

Allison’s New RHS Transmission Earns a Prestigious Award


Allison’s New RHS Transmission Earns a Prestigious Award

Allison’s transmission solution 3414 RHS is a good example of how automotive market needs facilitate progress of Allison products. Developed in accordance with the latest industry trends and demands of modern customers, the 3414 RHS unit is now gaining recognition from industry experts. Heavy Duty Trucking magazine named this remarkable transmission solution a Top 20 Product Winner for 2020.


According to the magazine, this new transmission deserves this award, as it combines a wide range of advantages (lightweight, robustness, productivity) that are valued by the customers. Considered to be an ideal transmission option for urban delivery tractors, this innovative unit was closely examined by professional advisory board to comply with the award’s criteria.


Allison 3414 Regional Haul Series™ (RHS) transmission


As a part of the Allison’s 3000 Series, the 3414 RHS unit is the lightest solution in the segment and has increased enhanced performance characteristics (410 hp and 1966 Nm). Thus, this powerful gear shifting unit can be successfully used in fleet trucks operating in mixed duty cycles.


Compared to AMT analogs, the 3414 RHS unit ensures much faster (up to 25%) speed-up capacity. Moreover, by utilizing Allison’s xFE feature, which comprises an internal gear algorithm adjusted for increased fuel efficiency, and FuelSense® 2.0 with DynActive feature, this transmission guarantees improved fuel saving (up to 8 %).


This product is backed by Allison’s 5 year/ 750,000 miles warranty, including towing services. Since there is no necessity to frequently deal with clutch repairs like in manual trucks, fleets with Allison-equipped vehicles can forget about unplanned downtimes caused by frequent clutch issues. Allison officials have no doubts that this promising transmission solution will gain extreme popularity among fleet owners, as this unit combines some unique characteristics (lightweight and productivity rates) with the proven durability of Allison products.
