Abstract
A simplified shifting assembly in which a shifting stick is moved in a straight line to control gear range and differential operation in the transfer case of a four wheel drive vehicle. A gear lever arm is shiftable between "high", "neutral" and "low" gear positions while a differential lever arm is shiftable from a first to a second position to lock the differential mechanisms of the transfer case. Special cam slots and cam follower members on the lever arms and on an actuating member movable with the shifting stick effect movement of the differential lever arm by disengaging from the gear lever arm and engaging the differential lever arm.
