I have 2 questions regarding transmission fluids:

1) How often should this be changed

2) Is this a DIY project?

Please let me know what I should do.

Thanks folks!

If your fluid hasn't been done for a while, probably good to do a complete flush.
If you use non-synthetic, change at least what is in the pan every 15,000 miles and you should be fine. If you use synthetic ATF (strongly recommended), plan to change what is in the pan every 30-45,000 and you should be fine.
If you go with synthetic, I recommend using one with a Group IV base (PAO)--
AMSOIL or Mobil 1 come to mind.

Mobil 1 ATF claims to be synthetic except for the base oil. I'm not so sure if there is any PAO or they used dino instead. BTW, I use Mobil 1 ATF myself and after 60,000 km it still smells and looks good.

1. I change mine yearly (~20,000 miles) It's cheap (less than $20) and easy

2. Yes, I suggest a new hose retainer (6842411-8; $3.47) for the tranny line

3. www.volvospeed.com repairs & maintainence>Bay 13 has great info/instructions, as does the Haynes manual for 850's (I recommend this to all 850 owners)
