<p>An automatic mechanical change gear transmission system (10) is provided. The transmisssion (12) is a splitter type comprising a main section (48) connected in series with a blocked splitter type auxiliary section (50). The auxiliary section blockers (172) and clutch members (164) are provided with ramps (218, 220, 222, 224) which will tend to align the blockers and ramps in a nonblocking condition under the influence of biasing spring (178) if the main section is in neutral. A control unit (38) receives input signals and commands transmission shifts in a sequence including shifting the main section into neutral and shifting the auxiliary section to a new ratio during each shift procedure.</p> |
