New tranny and New PNP and now flashing arrow!!! 850 1993

Since all else failed, I replaced the PNP switch and I still had problems, so broke down and replaced the tranny with a warranted rebuilt. The switch was installed about a week before the tranny, and the tranny has been in a week. All was fine until yesterday when, stuck in traffic and cruising at a whopping 2 mph, the dang arrow started flashing and mode selector lights starting blinking (econ/sport). The flashing lasted about 24 hours and then went out. I was freaked to see the dang arrow again so soon!

Is it the switch, or the tranny, or both??? I haven't taken it back to see if any codes set, but plan to do on Monday. Would like some feedback to prepare me for what the shop will have to say (which I'm afraid will be no codes, no problem).

Thanks for any help!!!!!

    You can read the codes yourself AND the codes are there, permanently SO they'll also be able to read them too.
    Why worry? It's got warranty.

      I know it's got warranty, it's just the thought that I've spent years fighting the last switch and tranny, and don't want to be starting again so soon! I figured I'd have at least a couple of years without problems..........ha!

        If they installed a Volvo reman trans, it came with a new PNP switch. It's possible that either the switch is misadjusted, there's another problem with the vehicle speed sensor (not included, transferred), interior mode selector switch and/or there's a wiring problem to a trans sensor (not impossible).

        Start by reading the fault code(s), pin #1 and report back here if we can help before you take it back. Any codes are permanently stored until one manually clears them.

          Do you know if the codes also include the date it was set? I haven't been able to read them, because I have no idea where to look, but wondered if the dates would help diagnose the problem.

          Thanks!
