TIPTRONIC-
In 1990, the 964 Carrera 2 was offered with Porsche's first fully automatic transmission (the Tiptronic). The transmission also permitted the manual selection of gears up to a point- if and when a gear selection was thought to be harmful by the electronic system, the transmission would not allow such a shift. For example, the transmission would shift up when maximum permissible engine revs had been reached, or move automatically down when the engine speed had reached a speed incompatible with the gear selected. An interesting point of note was that the transmission would always select 2nd gear for a start, unless a sprint was required, at which point the driver could select 1st gear. The fully automatic mode was achieved by shifting the gear selector into the "D" position on the gear shift plate. Conversely, to select manual mode, the gear selector would have to be shifted to the right into the short lane with "+" and "-" selectors. From this gate, the four different gears could be selected "manually"- forward pushes would select higher gears, pulling back the lever would select a lower gear. The Tiptronic system, whilst extremely competent, remained a weak link in the Carrera 2 given that there were only four gears on tap. Performance obviously suffered with 100kmh being reached only after 6.6 seconds, as opposed to 5.5 seconds for a manual Carrera 2.
Indeed, if five gears had been offered, it is most certain that an enthusiast would be far more likely to consider a Tiptronic equipped car for spirited driving. As was, the Tiptronic gearbox made sense for a large number of city dwelling 911 owners, who all too frequently got stuck in traffic. However, there were exceptional 3rd party supplied alternatives, such as the RUF E. K. S. system (to be described under Modifications).

..... Ik schrok me tandjes, daar ik dus dacht dat ik mijn Tiptronic had gesloopt.
Wat bleek nou (na twee rondjes nadenken en langzaam wit wegtrekken); de training werkte zo goed dat ik steeds harder ging en dus op hogere snelheid met meer toeren de bocht in knalde, waardoor ik de Tip nog niet in zijn 3 of 2 kon gooien, daar de toeren nog te hoog waren om te kunnen terugschakelen. Dat systeem werkt dus...
