'99 S80 T6 Transmission Problem
 

I had the transmission urgent service message come on and the central triangle orange light and the check engine message on the right. When I had it checked the technican added a quart of fluid. Afterwards the orange light went off, but the other two messages stayed. Does this mean that I solved the problem by having fluid added? Should the messages have reset themselves if the problem has been solved?

If he added fluid, you could have a leak. I would keep an eye on the level and see if it drops at all. As for the codes, clear them out and see what ones come back.

Welcome to VF. Please post tech problems in the model forum sections.

You may need to go to a dealer or Volvo specific garage to get the codes cleared.
