    Abstract: A parking mechanism in a vehicle is controlled to rotate, which engages and disengages a pawl with a spoke or gear of a wheel to selectively hold the wheel against rotation in park. A spring is connected to the parking mechanism at a first end, and is connected to the transmission housing or a stop block at a second end. The first end of the spring is a closed loop, such as a helix shape that extends over 360 degrees over a loop axis. The second end of the spring is open-ended, such as a hook. After attaching the first end of the spring to the park mechanism, but prior to attaching the second end, a valve assembly can be mounted as well as the stop block. After those components are assembled in place, the second end of the spring can simply hook into place.

    Abstract: A transmission diagnostic system includes a pivotable member and an actuator. The actuator has a notch with a first side, a second side, and an opening between the two sides. The width of the opening is greater than a width of the pivotable member. The pivotable member is retained within the notch, and the actuator is configured to selectively pivot the pivotable member between an engaged position, corresponding to a PARK gear, and a disengaged position, corresponding to a gear other than PARK. The transmission diagnostic system also includes a biasing spring configured to exert a biasing torque on the pivotable member to bias the pivotable member toward the first side of the notch. The transmission diagnostic system further includes a controller configured to generate at least one diagnostic signal in response to the pivotable member not being in contact with the first side of the notch.

    Abstract: A fastener having a head is provided. The fastener includes a unidirectional inner drive including an inner lobe having an inner ramp surface adjacent to an inner drive abutment surface adapted to receive a torque to effect a clockwise rotation of the fastener. The fastener further includes a concentric unidirectional outer drive including an outer lobe having an outer ramp surface adjacent to an outer drive abutment surface adapted to receive an inverse torque to effect a counter-clockwise rotation of the fastener.

    Abstract: A vehicle park lock assembly includes a park valve that moves in a first direction to transition a lever from a first to a second position, and moves in an opposite, second direction to permit movement of the lever from the second to the first position. The assembly includes a support block that limits movement of the park valve in the first direction. The assembly includes a biasing device coupled to the support block and the park valve. The biasing device biases the park valve to the first position. A method of supporting components of a vehicle park lock assembly includes moving a park valve in a first direction to transition a lever from a first to a second position, and moving the park valve in an opposite, second direction to permit movement of the lever from the second to the first position. The method also includes biasing the park valve to the first position with a biasing device that is coupled to the lever and a support block, and limiting movement of the park valve in the first direction using the support block.
