Abstract
The present disclosure relates to various shift selector assemblies having a shift gate with a plurality of indentations corresponding to transmission shift selections. At least one of the indentations is configured to have a flexible depth so as to selectively restrict and accept a pawl pin, thereby mitigating shift position overshoot.
Claims9
A method of mitigating overshoot in a transmission shift selector, comprising:
- providing a shift gate with indentations that correspond to different shift selections;
- and
- changing the depth of one of the indentations between a restricted position that blocks a pawl from engaging the one indentation and a receptive position that allows a radially outer surface of the pawl to contact the indentation.
A method of mitigating overshoot in a transmission shift selector, comprising:
- providing a shiftgate having multiple indentations of different radial distances from a pivot;
- moving a plunger relative to one of the indentations, producing a greater radial distance from the pivot that admits a pawl into the one indentation;
- moving the plunger relative to the one indentation, producing a lesser radial distance from the pivot that restricts the pawl from the one indentation.
A method of mitigating overshoot in a transmission shift selector, comprising:
- forming a shift gate with a plurality of indentations that correspond to different shift selections;
- altering the depth of at least one indentation in the shift gate between a restricted position and a receptive position;
- wherein the restricted position mitigates overshoot in a first direction and wherein the receptive position mitigates overshoot in a second direction;
- and
- wherein the altering the depth of the indentation includes spring-mounting a member with respect to the shift gate within one of the indentations.
