Mod list: FX350 w/SMF, acuity bushings and shifter upgrade, amsoil synchromesh, Sirimoto CMC and clutch line, CDV delete
So some back story... I had the classic high rpm lockout with aftermarket clutches. It wasn't terrible after I adjusted the master cylinder plus I don't drive too hard very often.
Then I started experiencing some complete lockouts. I'd start the car and couldn't get into any gear. Turning the car off and back on usually fixed it. It was concerning definitely, but it ran. Me and my friends had no idea what was going on.
Then it happened while I was driving. I turned the car off and back on and went on my way, but needless to say that was worrying me. I was looking into what it could be but couldn't find much other than the high rpm lockout threads. I could shift normally for the most part until I couldn't, which started about 2-3 weeks ago. I would go to shift, CMC adjusted all the way out, and can't get into any gear without hitting a wall until the revs drop. I replaced the CMC as I'd seen others do, but the problem persisted. We bled the system with a vacuum bleeder several times to no avail. I'm driving the car extremely gently now.
I've been thinking it could be the slave failing or a clutch damper spring failing/failed. I didn't think it was synchros since it happens in every gear. I'm planning on looking at the clutch with a bore scope and dropping the trans to take a look. I may be able to get a video later today... But if you guys have any insight on what's going on or where to look I would love to hear it! If you need any more info feel free to ask!
Thanks!
