Abstract
A method and apparatus are provided for manually shifting an electrically controlled transmission (14) to a desired gear setting in the event of a failure includes unlocking a manual shift mechanism (90) from a non-actuatable condition. The manual shift mechanism (90) is linearly moved from the non-actuated condition toward an engageable position with a link arm (70) to linearly move the link arm in response to further linear movement of the manual shift mechanism after engagement therewith. A transmission gear (16) is rotated to manually shift the transmission (14) to the desired gear setting through linear motion of the link arm (70).
