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.

ATSG Seminars


Each attendee receives a complete set of our well-known seminar technical manuals and a copy of the Presentation on CD. The seminar manuals are keyed exactly to the presentation. This allows the technician to follow the presentation and write additional notes right in the book for later reference in the shop.


The goal ATSG sets for its seminars is to bring the most pertinent information to the attending technicians. The seminar manuals can be used as references to the material covered when back in the shop, as the fixes outlined are needed. Recordings are also helpful in getting as much information as possible.

ATSG SUPPORTS VOLUNTARY TECHNIICIAN CERTIFICATION.

Our seminars will SAVE YOU HUNDREDS OF DOLLARS in lost time due to mis-diagnosed problems! The fixes and information in our seminars will help you get the job done right the FIRST time around.

The prices are per person and include the coffee, lunch and a complete set of training materials. If you will need accommodations, you must make your reservation 3 weeks in advance to receive the ATSG discount at the sponsored hotel.
