A measurement device includes a base extending along a longitudinal axis, an input connector configured for attachment to a shifter assembly of a vehicle and a clamp configured for attachment to a linkage support bracket of the vehicle. The measurement device measures the linear displacement of a linkage interconnecting the shifter assembly and a transmission of the vehicle in response to movement of the shifter assembly between a first position and a second position. A scale is attached to the input connector and slideably supported by the clamp. A scale reader is attached to the base for measuring linear movement of the scale in response to movement of the shifter assembly between the first and second positions. Preferably, the scale and the scale reader comprise a digital measuring unit having a digital display for displaying the measured linear movement.
