I have a 2001 S80 T6 with about 80,000 miles.  After having it in to the
dealer for some transmission work the steering seems to have a lot of play
in it while driving.  Driving down a straight road with no wind the steering
wheel will sometimes be cocked to the left a bit and then sometimes to the
right.  None of this was like this before the tranny work.  I have put the
car up on blocks; with the engine off there is no slop at all in the
linkage.  Also turning the steering wheel with the engine off gets instant
turn of the wheels.  My question: Does the S80 have speed sensitive steering
that may have been lost in the software update for the transmission or some
kind of electrical pick-up that may have been left off?

The dealer says nothing they did would have caused it.

Thanks for your help
