My 92 stx manual tranny sometimes has problems going into 3rd...it's not really hard to get it in 3rd, just kinda grinds alittle. It usually doesn't happen when I first run it...after it's warmed up it does it. Up or down shift...acts like it doesn't want to go into 3rd above 30mph. Any ideas....

Sounds like you need some tranny fluid. Check it out then post results.

Either what he said or your synchros are on their way out. I would change out the transmission fluid and go from there. I do it every couple years. Takes an hour of your time but it really helps. My 2nd was starting to grind again, replaced the fluid with pennzoil synchromesh and it's all good again.
