Abstract (en)
[origin: WO2009099884A2] A power train for a machine is provided having a transmission including a plurality of gears configured to produce multiple output ratios when selectively engaged. The power train also has at least one sensor configured to sense at least one parameter indicative of a condition requiring a disablement of a gear output ratio during a downshifting event. In addition, the power train has a controller configured to regulate the transmission in either a first or a second mode in response to the at least one parameter. At least one of the gear output ratios is disabled during downshifting events occurring while the controller regulates the transmission in the first mode. Furthermore, all gear output ratios are available during downshifting events occurring while the controller regulates the transmission in the second mode.
