A compound transmission is disclosed comprising a main section connected in series with a splitter type auxiliary section. A splitter clutch collar is fixed for rotation with a mainshaft and is axially movable therealong. In one embodiment, a blocking mechanism includes a pair of spaced apart rings having pins extending therebetween and through certain openings in a radially extending flange of the splitter clutch collar. Each of the pins has a shoulder cooperating with the associated flange opening for blocking engagement of the splitter clutch collar with either the mainshaft gear or a splitter gear when the splitter clutch collar and the gear to be engaged are not rotating at substantially the same speed. In a second embodiment, the blocking mechanism includes a pair of spaced apart rings having a plurality of legs extending therebetween and through certain of the openings in the flange. Each of the legs has a shoulder that cooperates with the associated flange opening to block engagement of the splitter clutch collar with either the mainshaft gear or the splitter gear until synchronous is achieved. In a third embodiment, the blocking mechanism includes a pair of spaced apart baulk rings. Each baulk ring has a set of chamfered teeth facing one of two sets of chamfered teeth of the splitter clutch collar. The opposed sets of chamfered teeth cooperate to block engagement of the splitter clutch collar with either the mainshaft gear or the splitter gear until synchronous is achieved.
