playing in the mud today (off-road site near pontardawe, excellent site for
25 notes for a day).This of course was mostly low box and mostly in 1st and 2nd. spent a large part of the day with 'box in 2nd or 3rd on the selector.
on the way back, it's forgotten how to use 3rd or 4th; not the end of the world, it's quite happy at speeds of up to 45 in second.
It selects neutral and reverse fine, pulls of fin first, changes to second, kicks down to first if asked to, the first gear inhibitor works, everything appears to work, but it won't go above 2nd. Kickdown cable seems to feel normal, too, and disconnecting it makes no difference to the shifting or lack of it.
Now the symptoms to me point to the 2nd gear lock dingus being stuck. Assuming that it doesn't free off overnight, when it'll have got properly cold, what sort of job is it to sort this? and BTW, anyone know of any other thing that might cause these symptoms?
I'm about to look in the RAVE thing and see if that sheds any light.
I do have a spare control block on the gearbox which died of a failed clutch. Since that box was working fine and still changing gear up until the clutch died, the only thing that might be iffy is that it could have a bit of contaminated oil in it - it has been drained, since I took the nearly-new filter screen out of it.
So I could change the control block, which would let me at the same time change the dodgy kickdown cable for the better one, and might also get rid of the rather fierce upshifts which this box has tended to have.
