Having a few problems for a change, 200tdi with LT77 Gear Box.

I have just fitted a refurbished gearbox, when it isn't running I can get reverse, first, second third and fourth but no reverse. It all moves through the gears fine except for the fifth.

Start it up with clutch pressed and still only get reverse, first, second third and fourth again no fifth.

Release the clutch with what should be in neutral and it is still in gear and lurches forward?

Anyone have any ideas? New clutch, fitted 1500 miles ago along with clutch master and slave cylinders.
 
if I remember rightly, 5th is out on its own, top right. either the 5th gear stop has moved in the gear lever housing (see below) or you have some issue with the 5th gear shaft.

not sure about why neutral isn't working, again probably some issue with the shafts.

can you feel and hear it engage the gears it does? take the top off and look at the quadrant on the shaft if you google frc7330 look at a pic the right angle cutout should sit on lhs of the box ie passenger side also google image frc4905 if you ensure 5th is in neutral it should sit over the raised flange on the interlock on selector shaft

Well I think I have found the problem.
The interlock spool isn't connected to the 5th gear selector fork

Now my big question, is there anything I can do to sort this out or does the gearbox need to come out and be stripped?

Any ideas?

if you knock pin out of the quadrant on rear of selector shaft and remove the front interlock on top middle of main case you can fully rotate shaft as long as 1/2 and 3/4 are in neutral
 
I am still having problems with this.

I have removed the quadrant and the middle interlock not a problem. selector will now spin but it won't lock in to the 5 gear selector fork, it is though the selector fork is too far back in the box. The interlock spool id a good 1/4" out from the selector fork.

it should if you lever 5th into gear by the selector fork rotate enough to go go forward to engage the fork slot
