Volvo tries to charge and arm and a leg and a pinky for their Volvo Transmission Fluid. The fluid is the same as Mobile 3309 transmission fluid. You can also use Toyota's T4 fluid as well. Both cost a FRACTION of the cost of what Volvo charges. And on top of this, I spoke with a transmission place, and they told me that a standard $80 fluid change is all that's needed and that you don't even need any "special" transmission fluid. This latter point is on you to decide. Speak with a transmission specialist and also research with Google about the Mobile 3309, you'll see.
