Stesaw wrote: ↑04 Aug 2024, 18:45 I have a 4 speed box.. ABD code if I remember correctly. Not using it but its kept dry and I turn it over every month. Although I've never dropped the plug so dunno if it has oil in. I just assume it has. Selects gears fine but thats no indication of the condition of it.

But be aware any used box may have unknown issues. All sellers will tell you it was fine when removed from the original bus, which was fine when they were £50 and there were lots of them tucked away in sheds 'as a spare' and if the first box you got wasn't good you could readily find another and you'd be quicker on the subsequent change. but 20 years later that ain't the case in my experience.
20 years ago you could put up a wanted ad on here and usually be offered 2 or 3 in a day or two, and another member would offer to deliver it and might give you a hand putting it in

Any decent garage could swap out the correct box (ie right box with correct bellhousing and input shaft so no messing) in 1/2 a day maximum; gear linkage 2 bolts, driveshafts 12 bolts, engine 4 bolts, starter motor another nut, battery disconnect, gearbox mount 4 bolts, clutch slave 2 bolts, and if fitting a new one clutch is 6 bolts, plus fresh oil, it's really only a couple of hours work on a ramp, three with a decent tea break. First time on your own yes a day's work.

M0cki is still much youger than me

If that is the case then you have a broken gearbox, could be broken tooth (or teeth) on crown and pinion or broken tooth (or teeth) on a gearset, but the jamming in reverse is usually the pinion teeth trying to climb over remains of crown tooth

Cause is usually a very worn pinion bearing, usually proceeded by box becoming noticeably noisy, when you are driving it backwards the pinion shaft is moving backwards and tightening the mesh of the crown and pinion
