I was reading the transmission and heating problems post, and saw some side comments about "cruise control". The cruise control in my 1982 Newell was not working when I purchased it 7 weeks ago, and I am having it checked now. Does the cruise control work off of air pressure in the '82, or is it electronic? I couldn't find any documentation on the cruise control in the two 3 ring binders of info that came with the Newell, and nothing in the prior owner's notes.
