Tiptronic S A97/01
General
The 911 Carrera and 911 Carrera S use the tried-and-tested 5-speed Tiptronic gearbox from the 911 Carrera MY 04. The torque and performance potential of this gearbox covers even the higher requirements of the new engines. The shift pressures have been increased to adapt to the transmission of the higher torques, in particular those of the 3.8 litre engine. An improvement in shifting comfort has been achieved through the fine-tuning of oil pressure buildup during the course of shifting.
