A Mazda may have hard shifting or “pop out” of third gear. This is caused by a failure of the related clutch hub(s). To correct the problem of hard shifting, the shape of the 3-4 and 5-6 clutch hub has been changed. A surface treatment has now been added to the 3-4 clutch hub to prevent 3rd gear from jumping out.
Dual clutch transmissions are like having two manual transmissions shifting together while being controlled like an automatic transmission. This is the transmission of the future because it is lighter than an automatic and is just as efficient as a manual transmission.
