Shift Linkage: Description and Operation

Gearshift Mechanism

Like all other Porsche vehicles, the Boxster (987) and Boxster S (987) also employs cable shifting in model year 2005. This prevents a transfer of unit movements and vibrations to the shift lever. As opposed to the previously employed shift linkage, shift and selector cables (which are able to withstand tension and pressure) form the connection between shift lever and transmission. The advantages of this system are reduced space requirements, low weight and above all the effective prevention of the transfer of engine movements or vibrations to the shift lever, without impairing shifting precision.

A shift throw reduction of approx. 26 % has been achieved on the Boxster/S (987) models while retaining the same ergonomic characteristics by moving the deflection point on the shift lever (see Synchronization). Also, play in the shift module under the shift lever has been reduced, resulting in a more precise gearshifting gate. The same shift console is employed on both Boxster models.
