similar 850 transmission code

Gentlemen, I have an 850T5 estate the other day the transmission refused to
start from 1st gear through to 4th gear. When you pull away it starts off in
4th gear. Local dealer says it's the 'gear selector switch faulty or out of
position'. Fault code 313. Has anybody had experience of this and is it
possible to reposition/replace the selector switch at home under normal
domestic conditions?
Many thanks for any help!

Yes, I did it on mine, I partly used this site:
http://www.volvospeed.com/Repair/pnpswitch.htm
and the factory service manual.

The hardest part was separating the switch section of the connector
from the assembly. I also made my own centering tool frrom some scrap
plastic.

Some folks have had luck just moving the shifter rapidly from P to L
10-20 times to clean the switch contacts. I believe this is a temporary
fix at best.

 

We had a similar problem that turned out to be a fault in the speedometer. I
believe it was a bad connection since the problem was resolved by taking out
and putting back the speedometer.
