Ok, I had trouble with the page too.

just go to www.transonline.com, then go to TotalTech Database (on the left), then SHOW ME 'Mercedes' and then click on Oil Pressures. That's where you'll see the picture (2nd pic down i believe).
Now the only thing i'm confused on is which one do i turn 3/4 turn clockwise? The one on the left in the image? The bigger one? And the other one, which way and how much should i adjust it?
Thanks for all the help. I just cannot wait to for the improvement in shift quality!!!!
