Just curious. What is the difference in trans fluid v motor oil smoke?
I love happy endings.Thought I would complete this post by relating how it all turned out. I took the car to a great fellow in Phoenix, Schulte Automotive on 7th Avenue and Campbell. A very good Mercedes mechanic, I might add. It was, in fact, the valve seals on the passenger (right) side that were the issue. Again, thanks for all the help and suggestions.
