5.5 quarts of oil. And a filter, obviously. If you're using the OEM drain plug you'll need a new crush washer, but they're pretty good about including one.
The 2.2L number is for manual transmissions. Get an automatic serviced by a dealer or mechanic. It's not as simple as changing fluids on a manual.
Diff is 1.3L. You'll need new crush washers for the drain and fill plugs as well.
Have you done brake fluid? That's supposed to be every 30K miles.
DIY for manual trans/diff fluid changes, with torque values.
