In the final race between the Charger and Supra you are lead to believe that the Dom is shifting and the car has a manual transmition but when the camera shows him pushing the gas pedal down further you can see that there is no clutch petal and the car is actualy an automatic. They should have at least put in a fake clutch pedal, they did put in a fake shifter.
In the final race between the Charger and Supra, Dom was not shifting gears, those cars have a stick shift on the floor to put into drive instead of on the stearing wheel. Dom was putting the car into drive from neutral.
First off the Charger is an automatic, and if you knew anything about cars you would know that he is shifting. This is made possible by an after market racing transmition which makes it possible to have an automatic trasmition that shifts without a cluth.
If you look closely he is shifting. That is a sequential shift shifter. there is no clutch pedal. You just push uf to go up a gear and pull down to go down a gear. It is used widespread in a lot of different kinds of racing.
