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.

New Pro EV-1 Lock-Up Torque Converter


New Pro EV-1 Lock-Up Torque Converter

The progress in development of new solutions in the field of torque converters is made in the automotive industry on a large scale and in auto racing in particular. Therefore, ProTorque Performance Products is taking a step further with a new product. The Pro EV-1 lock-up torque converter combines a reliable design and a lock-up technology to become a robust gearbox product.


This clutch solution has already been tested under extreme conditions. Among peculiarities of this new torque converter specialists point out the fact that the lock-up clutch doesn’t have any parasitic losses or clutch dragging while operating in non-lock-up mode. In terms of design this new product resembles the original EV-1. A modular torque converter system produced to operate with lock-up gearboxes such as the TH400, Bruno Lenco, the Pro EV-1 pairs ideally with many popular and well-accepted automatic gearboxes.


This innovative solution will be released in 2 configurations (with and without a lock-up) and will adopt many components from its predecessor. It is expected that this solution will provide racers with a competitive advantage due to its adjustability.
