Patent ID: 8286526

Claim:
An assembly for actuating a synchronizer in a transmission, the assembly comprising: a piston moveable along a longitudinal axis, the piston having a bore, the bore having a reduced diameter portion centered on the longitudinal axis; a shift fork connected to the synchronizer; a shift rail having a first and a second circumferential groove, and a first end and a second end opposite the first end, wherein the shift rail is connected to the shift fork proximate the first end and is operable to move the shift fork between at least two positions, and the circumferential grooves are disposed more proximate the second end than the first end; an apply finger supported by the shift rail proximate the second end, the apply finger extending perpendicular from the shift rail and having an extension that is disposed within the bore of the piston, and wherein when the piston is moved along the longitudinal axis, the reduced diameter portion of the bore contacts the extension of the apply finger and moves the apply finger and the shift rail in a direction parallel to the longitudinal axis in order to actuate the synchronizer.
