ABSTRACT:
The present invention is an improved key for an in-line transmission. The key is located within a channel in the shift shaft and selectively engages keyways of gears disposed about the shift shaft. A shift fork and collar axially move the key within the shift shaft by engaging and moving the base of the key. The key includes a shoulder which connects the head and the shank portion of the key, with the shoulder being thicker than the shank to cause more of the key to be supported within the shift shaft channel and thereby the key is better able to withstand the shearing forces which result from the rotational coupling of the shift shaft and the gears. The shoulder includes the portion of the key which extends out of the channel to the keyway and connects with the head, and which also faces the same direction as the head.
