Hi Rick:

Good points.  I was able to get the set-up specs for the transmission
control cable from Sun Valley Transmission Rebuilder's website plus
additional detail from Continental Imports site.  When I followed Sun
Valley's spec it did change the shift points.  The 300SE has the white
nylon adjustment vs. the metal slide that I see on the SEC.  The shift
points are now a bit earlier.  Still have the awkward flare from 2-3
when rolling away from a near stop.  I will go ahead and start moving
the T on the modulator forward one click at a time to see if it helps
firm up 2-3.  The response on all other shifts 1-2, 3-4 and at speed 2-3
seem normal and the manual downshift at speed feels rapid and firm as
well.  Worse case I'll end up with a hard shift from a few clicks
forward on the T but, that will not hurt anything.

I'll let you know the results in a day or so.  It'll take that long to
do this slowly.  By the way there is no difference in the set-up between
the Euro and the US models!

Regards,
Dick
==================

I read this first post last.
  That makes sense that the flare seems more noticable since the control
pressure adjustment caused earlier shifts.
 The control pressure adjustment is more tolerable to tweaking based on
driving style. You may want to tweak it now that you know where it is
supposed to be.
It has to feel right too.
  The control pressure adjustment will not change the flare between 2 and
3. That is the modulator or the transmission itself.
