update on tranny limp home 850 1997

I cleaned the grounds this morning and put the new battery (less than a month old) on a trickle charge for a couple of hours. The battery was originally at 25% , charged it until 100%. Car fired up and the transmission worked fine. I drove it for about 20 min and was able to get it into OD and the turbo kicked in. Worked great.

I'll have the new battery and alternator/voltage regulator checked. I'll gladly pay few hundred for a new alternator versus a few thousand for remanufactured transmission.

Thanks for the help and suggestions...

    Don't be in a rush to replace the alternator. measure the charging volts,
    confirm that the wiring is OK especially the D+ (The small wire to the alternator)
    A good alternator might not work if there's a problem with the wiring.

    Start by getting the Volvo wiring diagram for your model year.
    Get it free online.
    There's a special section for the alternator and charging circuit.
