A transmission includes an input shaft, an output shaft, a variator, a plurality of clutches including a first clutch, a second clutch, a third clutch, a fourth clutch, and a variator bypass clutch, and a plurality of gearsets including a first gearset, a second gearset, a third gearset, and a fourth gearset. Testing includes calculating a position of a point of exciting force on the basis of vibration exciting, and calculating a reaction force on the basis of a load detected and the position of the point of exciting force. The unbalanced targets in one embodiment are spaced at ninety-degree intervals from an adjacent target, thereby causing the spindle to first spin in one direction after a target has been struck, and then to oscillate or rock alternately clockwise and counterclockwise before finally coming to a rest. A print media transport assembly is located between the keyboard circuit board and an underside of the housing. Prior to assembly of the steering column assembly to the motor vehicle, the anti-rotation device may be moved to the engaged position to lock the steering column in a common rotational position. The guide member slides along the first and second mesh rings to absorb the bending displacement, thereby absorbing the displacements due to the pitching vibration and rolling motion.
