The Porsche 991 GT3, which debuted in 2013, initially only offered the seven-speed PDK (Porsche Doppelkupplung) dual-clutch transmission and did not have a manual transmission option. However, for the 2018 model year, Porsche reintroduced the six-speed manual transmission to the GT3 lineup with the 991.2 generation. This allowed enthusiasts to enjoy the tactile experience of shifting gears themselves.
