Abstract

See full text

A default-to-park mechanism for a transmission includes an output member, a rotatable plate, a latching mechanism, and a biasing member. The output member is rotatable to park, reverse, neutral, and drive positions. The rotatable plate is coaxial with the output member. The plate and the output member interfere with one another such that the plate is moved in a first direction of rotation by the output member and the output member is moved in a second direction of rotation by the plate. The plate is releasably held by the latching mechanism to prevent rotation in the second direction of rotation when the output member is in the reverse, neutral, and drive positions. The biasing member biases the plate to rotate in the second direction of rotation to return the output member to the park position when the plate is released by the latching mechanism.
