The outer gear is turned because of the interior gear, and as the gears rotate, fluid is drawn up from the sump on one particular side from the crescent and forced out in to the hydraulic procedure on the opposite side.
As auto pace improves, the strain within the governor builds. This forces the change valve about until the very first gear circuit is closed, and the 2nd equipment circuit opens. Considering that the vehicle is accelerating at light throttle, the throttle valve doesn't utilize A great deal strain in opposition to the shift valve.
The park position typically features a lockout functionality (for instance a button over the side of the gear selector or demanding which the brake pedal be pressed) which helps prevent the transmission from remaining unintentionally shifted from park into other gear selector positions.
