Automatic transmission cars have gained more and more forward speeds over the years going from six, the seven speed or more. The higher gear ratios are nothing but taller and taller overdrive ratios to save fuel. The reason manual transmissions have mostly stayed at six beats is one of complicated shifting an extra dates according to a patent from BMW. The patent says that the extra Gates make it more likely that a driver will make a mistake downshifting leading to possible damage of the car.
However, a new patent application has surfaced from BMW outlines a way a transmission using the clutch pedal can have seven or more forward speeds without worrying the driver will make a mistake and destroy their engine. The transmission would you some sort of fluid that physically blocks any year but the correct gear when downshifting when a voltage is applied. I want this technology.
