With these kinds of an arrangement, as extra oil is diverted by opening the valve, the effective displacement in the pump is diminished and fewer oil is sent to the motor, resulting in it to show more gradually.

ระบบเกียร์อัตโนมัติแบบดั้งเดิมหรือ ระบบเกียร์ออโต้แบบ คอนเวอร์เตอร์ คือ ระบบที่ใช้คอนเวอร์เตอร์และใช้น้ำมันในการส่งถ่ายกำลัง โดยระบบนี้จะมีใช้กำลังจากเครื่องยนต์มากกว่าระบบเกียร์ธรรมดา ใครที่นิยมความแรงและขับได้เร้าใจ อาจจะไม่เหมาะกับเกียร์ประเภทนี้ แต่ในปัจจุบันระบบเกียร์คอนเวอร์เตอร์ได้มีการพัฒนามากขึ้นจึงไม่ค่อยกินกำลังเครื่องยนต์เหมือนเมื่อก่อนแล้ว
The design theory dates back to prior to the 1930s, with the initial structure meant to convert rotary movement to oscillating motion and back to rotary motion applying roller clutches.[seventeen] This design and style stays in manufacturing as of 2017, for use with small-pace electric motors.
