Some weeks ago, I posted about some idling and electical problems with my 854. Because of your suggestions, most of those have been resolved, so I am greatly in your debt. I cleaned the throttle body, the battery contacts and spent some hours with the vacuum lines and some electical tape. Since then, the car has been behaving well, except:

It doesn't shift out of first until 4500rpm or so (enabling WINTER mode kicks it back down to 2500, but I've been told this is damaging to the transmission). Switching the gear shift down to 3 or L has no effect whatever (unless, again, in WINTER mode). The transmission doesn't appear to be slipping at all. I read the codes last week and nothing was reported to be wrong with the transmission. Yesterday, I had it flushed.

The mechanics I've spoken with are stumped. One tried to sell me a new valve body for $314. I politely declined.

any ideas?

Thanks,


Sebastian

P.S. I've been reading a bit about a PNP switch, which is associated with these types of problems. Is there any way to check this without replacing it?
