Not had a problem selecting 3rd or 4th ... but then I rarely do that at a standstill!  If the engine isn't running then you _can_ get failure to get it into any gear, or maybe have to try and select all of them before things move enough. Is it grinding when trying to select reverse but won't go in?  If so that's the clutch.  That can also prevent selection of forward gears but without grinding. Have there been any problems getting it out of gear once it has gone in?  Any unpleasant noises when you have selected a gear and are driving?  If not then selector problems and gear set problems are perhaps unlikely.  Also if the problem is with all the gears as you say i.e. all the fore and aft movements into reverse, 1st/2nd, and 3rd/4th then again selector problems seem less likely as there are three separate rods and forks.  The only common points are where the remote extension engages with the three rods which is accessed from the top of the gearbox i.e. a gearbox out job.  There is also an interlock plate which in that area which engages with that end of the selector rods and I think prevents more than one gear being engaged at a time. I can understand the problem coming and going with the clutch if sometimes the master cylinder is failing to pressurise the fluid and move the slave piston, more so than something having come loose inside the gearbox, with the possible exception of that interlock plate.

It's not uncommon to get problems selecting reverse or 1st, but lifting the clutch then trying again (if nudging towards 1st or 2nd doesn't work) has worked for me on two cars over 30 years.  Not had a problem selecting 3rd or 4th ... but then I rarely do that at a standstill!  If the engine isn't running then you _can_ get failure to get it into any gear, or maybe have to try and select all of them before things move enough.

Is it grinding when trying to select reverse but won't go in?  If so that's the clutch.  That can also prevent selection of forward gears but without grinding.

Have there been any problems getting it out of gear once it has gone in?  Any unpleasant noises when you have selected a gear and are driving?  If not then selector problems and gear set problems are perhaps unlikely.  Also if the problem is with all the gears as you say i.e. all the fore and aft movements into reverse, 1st/2nd, and 3rd/4th then again selector problems seem less likely as there are three separate rods and forks.  The only common points are where the remote extension engages with the three rods which is accessed from the top of the gearbox i.e. a gearbox out job.  There is also an interlock plate which in that area which engages with that end of the selector rods and I think prevents more than one gear being engaged at a time.

I can understand the problem coming and going with the clutch if sometimes the master cylinder is failing to pressurise the fluid and move the slave piston, more so than something having come loose inside the gearbox, with the possible exception of that interlock plate.
