Flashing Arrow (winter mode), but no codes - pls help 850 1996

1996 850 R, 120K miles. Transmission recently flushed a few weeks back. Prior conditon of fluid was decent (not burnt).

For the past few weeks, I have been getting the dreaded "flashing arrow".

Temp where I live - between 60-80 degrees in the day.

When it happens: After driving on the highway for 30 minutes or more and then it comes on while driving in the city. Ususally shortly after getting off highway.

What I've done to troubleshoot: My Volvo mechanic has scanned for codes multiple times, and he was even able to replicate the issue. No codes appeared in the system. We replaced the econ/sport switch as a quick, inexpensive fix, but the problem still exists.

What I'm wondering: Next steps to troubleshoot. I know that it could be the PNP switch, but without a code, I'm lost. What else might it be?

The other interesting point: the flashing arrow goes away when I throw it in Sport mode.

The tranny shifts & feels solid (also confirmed by mechanic).

Any help is greatly appreciated! Trying to fix this without spending tons of cash and just trying to guess what the problem is.

    Someone else was having the same issue over on volvospeed (was it you)...no codes...believe it ended up being the PnP switch.

      Yes - that's me. Just thought I might get a different cross-section of users here who might have had a similar problem. I think my next step is to install a new PNP switch, but the most complex thing I've done is to install a new Walbro fuel pump. I'm afraid of screwing up the tranny, but I'm also reluctant to shell out $250 for the mechanic to install the PNP when there's no code in the system.

      Have you installed a PNP before? How hard is it?

      Thanks.

          I have been trying to search for that thread, but no luck. I keep getting this error message:
          "One or all of your search keywords were below 4 characters or you searched for words which are not allowed, such as 'html', 'img', etc, please go back and increase the length of these search keywords or choose different keywords."

          because I type in PNP as one of my keywords...any idea where I can find it?

          Thanks.

            I found it...I just searched, "cleaning" and it came up! It's for an S70, but basically the same as your car: http://volvospeed.com/vs_forum/index.php?showtopic=45221&hl=Cleaning
