Ok this is totally weird.

I have been working on my firehawk and I'm having an issue with the transmission.

Lets say I'm going down the road at 35 and I'm coming to a red light. I push in the clutch and pop it out of gear. The light turns green, I'm doing 30 and I put it back into 4th and then it starts to grind while I push it into gear. I'll pop it out and put it back in and it grinds again. If I pop it out of gear pretty much on any gear it grinds when I put it back into that same gear. While I remind you the clutch is still held down through all of this. If I down shift it to 3rd and back up it goes in fine.

Someone said that it is the slave cylinder or the throw out bearing? Whats the cost on replacing these two items?
