A pneumatic actuator for actuating a shifting fork of a gearbox of a commercial vehicle, comprising: a pneumatic cylinder, the pneumatic cylinder comprising: a cylinder body defining a pneumatic chamber having a main axis, a cylinder head closing the pneumatic chamber, and a pneumatic piston for actuating the shifting fork, the pneumatic piston comprising: a piston head, a piston rod for connecting the piston head to the shifting fork, wherein the piston head is received in the pneumatic chamber slidable along the main axis between a coupling position and a neutral position, wherein the neutral position refers to a position in which the piston rod is configured such that it is not engaged with the shift fork and wherein the coupling position refers to a position in which the piston rod is configured such that it is engaged with the shift fork, wherein the piston head is configured such that it separates the pneumatic chamber into a first pressure chamber and a second pressure chamber, and a bypass fluidically connecting the first pressure chamber and the second pressure chamber, wherein the pneumatic piston further comprises a piston collar, wherein the cylinder body comprises a first seal, wherein the piston rod extends through said first seal, and wherein in the neutral position the piston collar is configured such that it engages with the first seal to separate the first pressure chamber into a third pressure chamber and a fourth pressure chamber. a pneumatic cylinder, the pneumatic cylinder comprising: a cylinder body defining a pneumatic chamber having a main axis, a cylinder head closing the pneumatic chamber, and a pneumatic piston for actuating the shifting fork, the pneumatic piston comprising: a piston head, a piston rod for connecting the piston head to the shifting fork, wherein the piston head is received in the pneumatic chamber slidable along the main axis between a coupling position and a neutral position, wherein the neutral position refers to a position in which the piston rod is configured such that it is not engaged with the shift fork and wherein the coupling position refers to a position in which the piston rod is configured such that it is engaged with the shift fork, wherein the piston head is configured such that it separates the pneumatic chamber into a first pressure chamber and a second pressure chamber, and a bypass fluidically connecting the first pressure chamber and the second pressure chamber, wherein the pneumatic piston further comprises a piston collar, wherein the cylinder body comprises a first seal, wherein the piston rod extends through said first seal, and wherein in the neutral position the piston collar is configured such that it engages with the first seal to separate the first pressure chamber into a third pressure chamber and a fourth pressure chamber. a cylinder body defining a pneumatic chamber having a main axis, a cylinder head closing the pneumatic chamber, and a
