Autobox can be a problem because Volvo didn't specify a ATF change interval. I.e. sealed for life. I'd get the fluid changed asap if you have no record of it being done. If you don't, the valve body suffers excessive wear. This leads them to stick and leak. The consequence is that it'll bang into gear when fully warmed up. Loads of guides around on how to do it. The ATF isn't rare anymore and not that expensive.
When changing it, it is critical that you get the correct level filled back into it. The way you do it is by measuring exactly what had gone out and putting exactly the same back in again.
Also the radiator circuit can leak into the ATF circuit and kill it even quicker. Not as often but still happens.
If the box is banging, don't fret too much. Hooli has my old Saab 9-5 that does it and he's put at least 10k on it in that state. The previous owner to me put similar on it from when it started banging too.
