If it grinds, that's your primary indication. Next to go will be 5th, then fourth. All the synchros will soon fall and getting the dog gear up to speed will be a chore for any gear at high rpms. I'm still waiting on my warranty replacement transmission because of this. Only a few people I've talked to here have experienced this.
