A system and method for completing an automatic up-shift during an engine progressive governor event in a controller-assisted, manually shifted compound transmission system (10) and splitter shift control therefor. Auxiliary splitter section (16B) shifts are automatically implemented by a splitter shifter (28) under commands (56) from a controller (48). The controller (48) overrides the engine governor control and controls engine torque to approach, and preferably reach a zero torque condition and bring the transmission to a splitter-neutral condition to enable an automatic up-shift when the splitter button has been selected or lever shift has been moved by the operator. Depending on the type of shift event, the transmission will automatically complete the upshift or the operator can manually complete the upshift after engine synchronization. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
