The bands are tightened round the ring equipment to forestall it turning, plus the clutches are utilized to lock the sun equipment and planets.
With no transmission, cars and trucks can be limited to one particular gear ratio, and that ratio would need to be picked to enable the auto to journey at the desired top velocity. In the event you wished a best speed of eighty mph, then the gear ratio could well be just like 3rd gear in many manual transmission cars and trucks.
