I've got a 1992 240 that's been acting a bit odd lately.  if I take it
out for a drive, stop driving it for a while (30 minutes to 2 hours, it
seems), and then drive it again, it has problems going from 2nd to 3rd
and oftentimes won't go into 4th at all.  I've driven it to and from
work every day for the past two weeks, though, and didn't notice the
problem once.  it's only if I drive, stop and then drive again a short
time later.  I've read posts about the kickdown cable and fuses, but
those seem to only apply to problems going from 3rd to 4th, so I wasn't
sure they applied in my case.  I'm hoping the oddly intermitent nature
of it will give somebody a clue as to what is going on.  my trusty
volvo tech wasn't able to find a problem, so he suggested replacing the
transmission but (as you can imagine) I'm a little loathe to do that if
I don't have to.
thanks!
