The aforementioned friction bands and clutches are managed working with automatic transmission fluid (ATF), that's pressurized by a pump after which you can directed to the suitable bands/clutches to get the needed gear ratio. Internal-combustion engines run at large speeds, so a reduction in gearing is important to transmit ability https://gearbox-auto20751.blogoxo.com/33893340/the-basic-principles-of-gearbox-auto
