Changing Gear - Porsche 2012 911 GT3 CUP Technical Manual

5.7.

Changing gear

A gear lever force sensor is integrated in the gear knob, which activates
an ignition cut, and therefore a cut in propulsion, when pulled or pushed.
This allows full power up shifts to be made.
Attention: It is absolutely necessary to change gear as quickly as
possible. Shifting gear too slowly can cause an increase in wear or
damage to the dog-ring teeth.
