My 2005 S2000 makes kind of a weird clunk noise when i shift it into second gear. I can feel like something is kind of pushing it back when i go to put it into second like it doesn't want to go in right away unless i put more effort into it than the other gears. It makes the same noise when shifting into 3rd but way less noticeable and i don't experience that feeling of something pushing it back. Any help would be appreciated.
