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.

Abstract: An override mechanism for a shift-by-wire transmission includes a housing having a first pin aperture and a shaft extending into the housing. The override mechanism further includes a reel plate having a second pin aperture. The reel plate is rotatably fixed to the shaft and rotatable within the housing. The override mechanism further includes a spring biasing the reel plate to a first angular position, and a pull-pin removably disposable within the first and second pin apertures to retain the reel plate in a second angular position.

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 pawl return spring includes a surface contacting portion adapted to contact a transmission housing. The surface contacting portion includes a first connection region and a second connection region opposite the first connection region. The pawl return spring includes an active coil region connected to the first connection region and disposed about a central longitudinal axis to provide torsional effort to the system. The pawl return spring also includes an inactive coil region connected to the second connection region and disposed about the central longitudinal axis that does not provide torsional effort to the system.
