Patent ID: 8635925

Claim:
A shift inhibitor apparatus for a multiple speed transmission main section, the transmission including an input shaft and an output shaft, the transmission main section having a plurality of selectively engageable ratios, and the transmission also having a range section shiftable between a range high ratio and a range low ratio, the shift inhibitor comprising: an interlock moveable between a locked condition and a released condition, wherein said interlock selectively prevents a gear shift in the transmission main section when in the locked condition, and wherein the interlock is selectively moveable by a fluid pressure applied to the interlock; a range sensor valve, wherein said range sensor valve directly selectively detects a completed range shift of the range section, said range sensor valve selectively causes said interlock to be positioned in the released condition upon detection of a completed range shift, and wherein said interlock is selectively positioned by a fluid; and a shift member, wherein at least a portion of the shift member is a shaft portion rotatable to selectively engage the input shaft with the output shaft.
