Klaus,
Thank you very much; I genuinely appreciate your help. I have a very dumb question: PNP switch, is it the tranny micro switch? If not, what is it? I am not all that familiar with Volvos but am learning now that my daughter has graduated from college and the economy is such that there is not currently a great demand for commercial building Interior Designers; the 850 will live in our drive for a while. I am pretty good with BMW's, Alfas, and VW's (air and diesel). That said, I've not heard of the PNP switch.

Another symptom this car has is that the cruise control does not work. It abruptly quit last winter. I've not yet checked the switch at the brake pedal but perhaps all of these maladies are related.

I did the Volvo timing belt this last spring and I was really impressed on how straight forward these Swedes do things. Now that I've done one, I bet I could do it again in about 2-3 hours; water pump included.

Thanks and I'll get my Volvo-partner-daughter to assist with the diagnosis.
