Abstract: A transmission includes a transmission case, which defines a generally cylindrical bore that is sufficiently configured to pilot a fastening block member therein. A generally annular groove is defined by the transmission case and is sufficiently dimensioned to receive a snap ring. The snap ring operates to limit the axial movement of the fastening block member with respect to the generally cylindrical bore. An extension housing having a hub portion is also provided. A flange portion extends generally radially outward from the hub portion. The flange portion defines at least one bore that is sufficiently configured to receive a threaded fastener. Similarly, the fastening block defines at least one threaded bore sufficiently axially aligned and configured such that the fastener can threadingly engage the fastening block to secure the extension housing with respect to the case.

Abstract: A method for automatically calibrating a transmission of a vehicle using load sensing includes sensing a change in ride height of the vehicle and measuring a magnitude of the change in ride height of the vehicle. The method includes selecting a predefined set of parameters to calibrate the transmission depending on the magnitude of the change in ride height and calibrating the transmission using the selected predefined set of parameters.

Abstract: A torque-transmitting mechanism includes a spiral spring, an apply piston, and a rotating mechanism. The rotating mechanism is operative to rotate a member relative to the spiral spring to enforce linear movement of the spiral spring which results in linear movement of the apply piston to enforce engagement and disengagement of a torque-transmitting mechanism. The mechanism has two applications—interconnecting two rotating members, or connecting a rotating member to a ground member. The mechanism is employable in two systems. A motor drives the spiral spring with the rotation of the spring causing it to thread between stationary pins to move spring material to one side of the pins. The spiral spring pushes against the clutch plates. The motor drives the housing with pins and the spring is retained from rotating causing the spring to thread through the pins and drive the pins forward or backward. The housing presses against the clutch plates.

Abstract: A torque-transmitting mechanism having a latching apparatus includes a frictional drive connection between two components of a transmission mechanism. The torque-transmitting mechanism is controlled in engagement and disengagement through an apply piston to which an apply component is presented. The latching mechanism will prevent disengagement of the torque-transmitting mechanism even when the apply force is disestablished. The latching mechanism is provided with a controlled release to permit the apply force to be reestablished and thereafter control disengagement of the torque-transmitting mechanism.
