4-Speed Manual Transmission

To start the engine, press the red button on the bottom left.

Press [D] to simulate acceleration;
Press [W] to upshift;
Press [S] to downshift.

It has a handy tachometer that reaches to 9000 rpm.
Currently, I did not add a way to turn off the engine.

This is a very basic 4-speed manual transmission that you can inspire yourself from to build your own vehicles. (Credit would be appreciated but not necessary)

The reason I didn't make a vehicle with it myself is because I'm really bad at designing vehicles lol
