OK. Go outside, right now (well at least wait until you finish reading this) and do this...
1)Crank the car and put the car into drive.
2)Press the brake firmly
3)Now, try raising your RPMs to just under 3000
4)If you did not run into a wall or something, come back and tell me how it went.
No! The transmission only shifts into neutral when the shifter is placed into the neutral position.
