Which Mityvac?

2005 Volvo XC70

After reading a number of posts on how to change the "bevel gear oil" (which I've deduced is Mobil 3309ATF)in my Volvo, I'm ready to buy a Mityvac hand pump unit and give it a shot. I may use this same device for an ATF change as well.

Which model suits these tasks best?

Don't buy the small one. Capacity is too small. Use their larger ones or any of the other oil extractors out their.

So, Volvo is using ATF in the known to fail bevel gear? If that is the case, I'd think that a GL4 manual tranny fluid would be a better choice!
A VOA and UOA on this fluid would be interesting.
