ive had my car for about 6 mths now and when i first got it i somehow got it to chirp third gear pretty good but now when i do it it dosnet do it and i hear like a squeak like a belt ot something i was wondering what that could be.

 

Belt sqeak. Common issue. You can change the belt to a gator back and that helps a lot. Some people say it is the belt sliding on the plastic idler and suggest changing to a steel one.

Funny I have never been able to chirp third, the belt always slips though.
