I just had my 1995 850 repaired (turbo drain tube seal was leaking). That was four days ago, and I've only driven about 15 miles since.
Today I pulled out of my driveway and the engine warning light came on, along with the winter mode arrow, which is flashing.
There's only one gear, and the car won't accelerate.
Could there be some connection with the seal replacement?
I'll have to nurse the thing to the other side of town in the morning and leave it at the dealer's, and, as you can see by my login, I live in a very hilly area.

your car is in winter mode, the tranny skips low gears and starts out in 3rd i believe.

try working the winter mode switch, it may be stuck

The seal replacement you just had done has absolutely nothing to do with the tranny. No shared components, different location, completely separate.

You may have a PNP switch on the way out and you're operating in "limp home" mode.

More information on what it is and what it does can be found here:

I'm assuming that since you had a shop replace your oil return pipe seals you don't do your own maintenance. If it is the PNP switch, it's about $90 - $100 (fcpgroton.com) and a couple hours labor to install. So for a shop I'd expect around $400.

Good luck,
