Help with tranny!
You (or he) may also have broke/stripped the 3rd gear synchro's/blocking rings/keys (take your pick).
The best thing to do is break it down, and see what is broke (unfortunately) and then buy the parts necessary (unless you are gonna have it rebuilt)
I approached every angle. New fluid, new hydraulic fluids and bleed again. I had the same problem with 3rd gear, would grind like crazy yet I could start off in 3rd from a stand still. 5th gear grinded as well and I couldn't engage into reverse when I was already rolling down a hill in neutral (from my drive way).
Just sharing what happened with me.
