1. My car has 1600 miles ans it gets harder to get into 4-5-6 gears.
No grinding, but just I need more power to put it in. It was ok before 1500 miles.

2. When the clutch is depressed I hear a very very light sound comparing to pressed clutch. Is this ok. Again it was ok some time ago.

 

take it in and have it looked at. make sure they put in their computer that you had a complaint and make sure you get a documentation of your complaint. there are known issues with the manual tranny. do a search on this site.
