After geting my hands on a proper repair manual along with the information provided in this thread it was clear that I simply have the incorrect valve body installed. Fortune enough there is a massive chrysler dealer over here. For $70 I'd call it a good deal.

In a week or so I hopefully will not have any problems to get my car rolling. As for the "kickdown linkage" I created something myself with copper tubing, bicycle wire and a return spring. Similar to what Lokar sells, but at the cost of $20.
