3rd gear grinds!

[1slowdsm]

I had some guy (who I thought was with TRE) rebuilt a stock tranny for me and I payed in PayPal (which I thought was strange for a company like TRE also). I still dont know how I got his e-mail. The only sites I remember looking at were ShepRacing and TRE for transmissions. So pretty much I did have get my new tranny from some unknown guy. Do you guys think that my adjusting the clutch pedal a little would help with this problem? I still dont get how it could Not downshift into 3rd, but upshift into 3rd fine. I'm not any smart with transmissions also, so I know VERY little.
