It sound like the gears engagement dogs are rounding off which is very common on many transmissions (especially 2nd gear)

I can get the trans undercut at Fast By Gast for you (they are undercut a little from the factory). They do excellent work and I am setup with them. I have had numerous transmissions done by them and all shift better then new when I get them back. You'll want to check and probably replace the shift forks while you're in there. Also, look the drum over carefully as they wear too. Typical price runs between $350-$500 depending on how bad the trans is. They can generally hard weld any heavily worn dogs and re-cut them. It's cheaper then a new gear would be but just as strong (or stronger).
