In an AT, pressurized computerized transmission fluid (ATF) is routed to clutch packs that lock and unlock the planetary gearsets. Transmission gear and gear ratios are fastened and based on which elements of the gearsets are freewheeling or staying held stationary from the clutch packs.
By obtaining an infinite amount of gear ‘ratios’ to differ in between, as opposed to an cerita penuh... everyday computerized Which may have just six or seven, a CVT gearbox can continue to keep the motor in its optimum rev range extra of enough time.
