DCTs are well-known in functionality and luxurious automobiles, in which motorists price responsive and sporty driving traits.
Planetary Gearset Ratios One of the planetary gearsets from our transmission has a hoop gear with seventy two teeth in addition to a Sunlight equipment with 30 tooth. We can get plenty of various equipment ratios out of the gearset.
Shift valves provide hydraulic force to your clutches and bands to engage Every gear. The valve entire body on the transmission has many change valves.
