If it makes noise in any other gears I can't hear it. It definitely goes away completely when you push in the clutch. Seems a little quieter once warm but that could just be wishful thinking. I changed the oil in the transmission. I got a few metal flakes out, but not much. Also, 5th is MUCH worse than neutral. In 5th you can feel it hit hard with your hand on the shifter. Luckily this is not my daily driver. I haven't moved it much anyway and not any in 5th gear. I'm still having a charging issue as well that I can't quite trace down. I'm thinking a bad ground at this point.
Wayno, I was really hoping that would not be the case, but I fear you are correct. I've never rebuilt a transmission before. First time for everything I guess. Is there any (realistic) way to get at this without pulling the engine?
