Check to make sure that both cables are moving freely, mine would grind a little when down shifting then one day wouldnt go into any gear. I thought I had blown my trans, 6sd:-( but while replacing I found a stuck cable. Still a huge pain to replace but cheaper than a trans.
Since the thread was bumped any update for us?
Again if you need we can take care of the trans work needed just ask around we have been doing lots of transmissions lately seems that most are getting tired and needing to be freshened up for more beatings.
We can get oem parts to replace your worn items and can get you specific gears for what you prefer.
