Abstract
A compound change gear transmission (11) of the type including a multiple speed ratio main transmission section (15) and an auxiliary transmission section (17), and a shift rod (83) to engage selected main section gear ratios, and a shift rod (85) to engage selected auxiliary gear ratios. An interlock assembly (91) is included of the type having an interlock pin member (103), which normally prevents axial movement of either shift rod when the other is displaced. The shift rod (83) for the main transmission section has an interlock deactivation position corresponding to a non-neutral, predetermined gear ratio of the main section. The shift rod (83) defines an interlock recess (105) which receives the interlock pin (103) when the shift rod is in the interlock deactivation position, thus permitting simultaneous axial movement of the shift rod (85) for the auxiliary section.
