A shifting mechanism for a multi-speed manual overdrive (OD) transmission. A "flipper" (206) reverses the action of the shift stick (128) for the final stage shift fork (152) to maintain progressive "H" or "HH" shift patterns yet engage a direct drive coupling as the next-to-last range and OD as the final engagement. The mechanism employs a quadrangular frame (214) slidably received on two adjacent shift rails (174,176) in a shift rail array. The frame has one side above the shift rail array notched (228) to engage the shift stick end of an opposite side below the array. The flipper is pivotally mounted below the array with one end engaging a notch (224) in the frame and the other end engaging the final stage shift fork so as to minimize bending stresses on the fork end and reaction loads of the sliding frame on the shift rails. <IMAGE> |
