Agreed --- also an adjustment on the vacuum control unit might help. I was of your same opinion about the Bowden. As stated before, my 300 SD was flaring and I suspected that I had larger project ahead than it turned out to be. A simple adjustment of the Bowden made shifting superb. On the other hand, when I bought my 300D a few years back, I wanted to tweak the shift. First I replaced the transmission modulator (it would not hold a vacuum) but no real improvement in the shift. Finally adjusted the vacuum control module (behind the injector pump on the 300D) and got the shift I wanted. Was prepared to repeat that trick on the SD but was relieved that the Bowden took care of it. Not quite what I expected, but was happy that a 5 minute job with no tools cured the flare.
