I have just replaced the clutch and put a different g'box in the zook and the box i took out looked similar but on a closer look it had no breather and had one less switch screwed into it. Any idea what it was from?
is it a sierra box or is it from a cary van or something???
BTW second gear sincro was stuffedthus the swap

Yeah had the same prob on the weekend
Think the one with three switches is the early and the one with two the late model box
I just swapped the switches over so I did not have to hack the wiring loom as the plugs are different
Should check to see if my reverse lights work

If the one you put had four then one that come out had three
Which is the same as the one I took out which was from '85 NT

Read it slowly, it makes sense
You did not say how many switches was in the box you you took out

I think it was whats left is Right but whats Right may be left, if thats right then whats left should be right...!?
or something like that...
not really to sure, but i think he wants you to count the switches and try swapping them.. may be wrong but thats the best i can come up with!

Got a pic of the box and switches??? Only 1 of them are used from the reverse lights others are used for 5th gear and emmisions control.

It should have a breather. All gearbox's need then, otherwise as they heat up they build pressure, forcing oil past seals etc.

Early gearboxes didn't have a separate breather on the top of the gearbox. My 85 SJ413 didn't have one.
Instead they have a little hole in the back of the shifter tower. Quite a pain in the ass as they piss oil out on really steep climbs / winches.
They also have less switches in them.
