Sorry if this is a double post....

About this "conductor Plate"
I changed the tranny fluid with MB spec 236.10
thought it might get rid of the slight...."hard shift" between 1-2, 2-3. Its not annoying but still not MB smooth.
What actually happens to the speed sensors anyways? oil contamination? Whats the root cause here....I guess I'm asking the 5 whys....?????

For $200+post I thought its probably worth while and looking at the vid - although I would be doing it upside down....looks like semi DIY.
