Abstract: A gear selector inhibitor and warning signal switch for the power transmission gear selector mechanism of an automotive vehicle having primary torque drive gears and an idler pinion selectively engageable with a drive gear. The inhibitor and switch unit includes a spring biased plunger that urges engagement of the plunger with a bellcrank, which is adapted to move the idler into meshing engagement with the drive gear when the gear shift mechanism transmits shifting motion to the bellcrank. In this condition, the plunger is forced by the shift mechanism out of engagement with the bellcrank and this action operates to make a connection between electrical terminals on the plunger and electrical receptacles for the terminals thereby completing an electrical circuit that produces a sensible warning indication that the shift mechanism has engaged the bellcrank.

Abstract: A multiple ratio power transmission mechanism for an automotive vehicle adapted for mounting in transverse disposition with respect to the fore and aft centerline of the vehicle and comprising a torque input shaft with torque input gearing adapted to be clutched to the crankshaft of the engine and countershaft gearing meshing with the torque input gearing, synchronizer clutches associated with the gearing, a geared differential establishing a driving connection between the countershaft and each of two drive wheel axle shafts, a single shift fork rail adapted for axial and rotary movement to effect engagement and release of the synchronizer clutches, a shift selector control shaft situated in transverse disposition with respect to the axis of the shift rail and a right-angle drive lever mechanism for connecting driveably the shift selector control shaft with the shift fork rail to effect transfer of rotary and axial movement to the shift rail and to cause corresponding movement of the shift rail for speed rati
