I am kind of winging it here so bear with me. I recall a similar problem
with my tach a few years ago when I replaced the cable. The inner cable goes
into the outer sheath only one way. You can pull it all the way out and one
end of the cable has a stop on it so when you put it back in, it won't go all
the way through. If the stop is on the tranny end instead of the speedo end,
it is possible that the cable is engaging in the tranny too deeply which
means it may be slipping out of the speedo engagement. Everything spins OK
but
it just is not engaging in the female part of the speedo mechanism. Look and
see if the little brass disk that is the stop is on the speedo end rather
than the tranny end. I think this can be reversed by pulling the cable out of
the sheath and feeding it back in from the other end. My tach just stopped
working, then started again then stopped again. After close inspection I
reasoned this was the problem and this has not happened again since. Again.
it
has been a while.
