Transmission may need to be replaced, but that's just a guess. You need to retrieve the codes and post them back here so we can figure out what's wrong.

First "row" the shifter back and forth about 15-20 times, engine on, brake on.
If this helps, you have a bad PNP switch that will need to be replaced ASAP
However, if after the switch is replaced and you still have a problem, your tranny has packed itself in.
You need to have the codes read at a Volvo dealer a generic reader will not do

I have the same problem with my 1998 C70. I had no problems with it and suddenly the CEL and flashing arrow came on. It does seem to hesitate slightly when shifting once those lights came on. I added clean transmission fluid, as it was low. Can it be driven to the dealer like this - what are the odds that the entire transmission needs replacement, rather than just the PNP switch, or that it could be a sticky mode switch?

Anytime you get the flashing arrow you will get a CEL - I guess they just wanted to add urgency to the issue when they wrote the firmware for the ECU and TCU.

9 times out of 10 it is a PNP switch problem at least with my 850s. On the 850s I can read the transmission codes just fine with a standard OBD-II scanner, on the later models that may be different. I will defer to JRL since he has much more knowledge on the later model cars than I but I thought that federal law required that any power train (P) code be readable via an standard OBD-II scanner.

Once the flashing arrow sequence is initiated it has usually gone into "limp home" mode which means that the car is basically stuck in 3rd gear. Anything beyond "limping home" is really tough on the transmission internals. A series of short trips shouldn't kill you but limit driving as much as possible until the problem is dealt with.

Thanks. I tried rowing the gearshift lever, but the flashing arrow and CEL are still on. Additionally, and I did not notice if it was doing this before, but the mode selector is switching back and forth between "S" and "W", or "E" and "W". The light is blinking back and forth between the 2. It is also revving pretty high. The volvo dealership is 25 miles from my house, so I do not think I should attempt to drive it there. Any advice or thoughts on this?

If all of the dash lights came on also,the the ABS module could be the issue,also the electrical side of the ignition switch is know to cause this.
When mu ABS module went bad the das looked like a christmas tree.

Nope, the dash is fine. I just have the CEL and the flashing arrow on the dash, and now the back and forth lights on the mode selector switch below the gearshift.

You can make it 25 miles with no problem but accelerate slowly, the car will act like it has an anchor tied behind it when you leave from a stop but don't floor it to try to overcome that. Hopefully much of the 25 miles is highway without a lot of stop and go starts.
