Transmission Models & Technologies

CVT, DCT, Tiptronic, Powershift and Other Transmission Technologies

Technical information on automatic transmission models, gearbox families, design features, control systems, hydraulic layouts, electronic technologies, and transmission-specific engineering solutions. This section helps rebuilders, transmission specialists, repair shops, and parts professionals understand how different transmission units are designed, identified, serviced, and supported with the right components.

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.
