4-matic, Hydramatic with 3, Dynaflow with 2, or CVT with one. Why so many types of transmissions to do exactly the same task?
Automatic transmissions are a bust. The VW had the Automatic Stickshift, which was kind of an automatic, mercedes has the 4-matic, Hydramatic is the most common with 3, Buicks have only two speeds with dynaflow, and MINIS have the BMW creation the CVT, one speed (kinda).
The question is WHY? so many ways of making your ride even less reliable with MORE movng parts?
