Well, an 02 looks a lot like an 01 so I would guess they hold about the same quantities. Looks like you have determine which transmission and t-case.
From the 02 FSM:
Transfer Case:
NV241 = 4. 61 pints (2. 18 liter)
NV241 HD = 6. 51 pints (3. 08 liter)
Manual Trans:
NV4500 = 8. 0 pints (3. 8 liter)
NV5600 = 9. 5 pints (4. 5 liter)
