Abstract:

A control for enhanced range shifting in a computer () assisted vehicular compound transmission having a main section (A) shifted by a manually operated shift lever () and a range section (B) shifted in response to operation of a range shift selector, such as sensing shift lever () passing through a predetermined actuation point (AR) in the shift pattern. During a compound up-shift, if the vehicle reaches a speed greater than a predetermined value during a coasting condition and the shift lever is in a low range neutral position, then the range section up-shift is automatically completed without undue wear or damage to the range section synchronized clutch ().
