If you do get the transmission serviced at another garage, make sure they reset the transmission adaptions and fluid counter. Basically, you have to tell the car that it has new fluid (fluid counter reset) and reset the adaptions so the car adapts to changing with the new fluid. Resetting the adaptions isn't compulsory though, as the car learns how to shift itself anyway over time. Any reputable garage should do that as part of a transmission service though, particularly a Volvo Specialist.
