A method of detecting synchronizer misalignment in a vehicle transmission, includes: applying an engagement force to an input side of a synchronizer or output side of the synchronizer; monitoring a performance characteristic of a power source configured to apply the engagement force; and determining a misalignment based on the performance characteristic exceeding or not achieving a predetermined threshold.

Method of aligning a transmission synchronizer

The present disclosure relates to methods of detecting misalignment in a transmission synchronizer and methods of alignment. Detection of misalignment is accomplished via monitoring a performance characteristic of a power source configured to provide an engagement force to the synchronizer. Where misalignment is detected a predetermined torque is applied to the input or output side of the synchronizer to rotationally align synchronizer components.
