Difficulty selecting 3rd & 4th gear

[Terranical]

My 1994 T2 has suddenly developed an odd gear selection problem i.e. it changes up from 1st to 2nd perfectly, but changing from 2nd to 3rd and 3rd to 4th requires real pressure on the gear lever, as does changing down again from 4th to 3rd - changing to 5th and reverse is fine. This happened during a journey, with no warning, one minute perfect, next minute almost needing 2 hands on the gear lever to go from 3rd to 4th. Anyone got any ideas?

Having looked at the manual 3rd and 4th are operated by the same fork directly from the gear lever, so either the selector fork has got tight on the selector shaft, or something has broke like one arm of the selector fork so now it is pushing one sided, which will make it bind up, if you remove the gear lever and top cover you may be able to see it, but if it has broke? I have not worked on these boxes yet, but I doubt that it can be replaced with the box in situe, but I could be wrong, Rick Meant to have said if box low on oil first to suffer will be stuff at top of box so check oil first.

Thanks guys, certainly gives me something to start with.

It could be down to clutch drag, check the pedal box is tight, the top bolt has a tendency to come loose and the bracket bends (eventually cracking) when the clutch is pushed down loosing some of the pedal travel to the master cylinder.
