How does misusing a gear box damage a car?

I bought a car and it works really well. For the passed month now and again I change gears very lighyly when driving and the stick goes in neutral on a high speed and makes a screech noise. I have now started applying more pressure to avoid this.



What damages have I done to the car by doing this now and again?How does misusing a gear box damage a car?

hmmmm this sounds like there is a serious issue with the detents that hold the stick in place with the forks, what is most likely happening is the forks have shifted slightly and are rubbing against another gear causing the squeel, or causing the synchros to misalign. probably not a good thig:)
