Once Again "4KQ shift linkage"

[Av8or]

My 4KQ is suffering from a shift linkage problem of some sort.

1st gear is very difficult to get into, in fact I have to push down on
the
shift lever as if engaging reverse in order to hit it.  The others are
notchy and sometimes troublesome as well, especially shifting while
under
power.   I sprayed silicon on the plastic ball at the bottom end of the
shifter and this helped quite a bit, but the problem remains.

Are there any adjustments I can make?  Will a short-shift kit replace
the
problem parts?

TIA!
