Tranny not shifting good

[fedezyl]

Well, it could be the synchromeshers, does it make the grinding noise when you downshift? If you said that you have new fluid in it my bet is that the synchromeshers have gone bad on 2d and 3d, or whatever gear you downshift to, if that's the case you have 2 solutions, the expensive one, take out the transmission, take it apart and replace the synchros, the second one, a bit annoying maybe is to do heel and toe downshifting...
Now, i've broken a synchro before downshifting when at the race track for not heel and toeing...and it makes that grinding noise when you shift after it's broken...
hope it helps...
