Short version took trans apart put new 3rd gear synchro in resealed trans through it back in filled with fluid started car and as soon as you let off clutch while in neutral or any gear the car dies. Bled the clutch same issue. It will row through all gears while clutch I'd depresses and while car is off but as soon as you let off clutch it's dies doesn't matter how high you Rev it. If in gear and you let off the clutch it does nothing but shut off doesn't lurch doesn't try to do anything. Had no issue previously other then 3rd gear synchro. I'm gonna run back through everything tomorrow before pulling the trans back out and splitting the case. I've found many threads of very similar issues but no one replies with what the cause or fix to the issue is someone helppppp.

 

You did something wrong in your 3rd gear synchro install. Pull the transmission and open it up.
