I've been having problems with my transmission these past few days. The biggest problem is that when I shift into 2nd, it grinds just a little bit but then it goes into the gear and works fine. My mechanic said it was a problem with the syncro and I need a new transmission. Also, sometimes it's pretty hard to shift into 1st or 2nd gear. It'l go but it just takes a little force, like it's getting caught on something, but it still feels like I'm hurting it or something. So I'm wondering, what is wrong, what needs to be replaced, and how cheap can I get it replaced for? Thanks in advance.
