Little safety trick: When replacing transmission or differential fluid always remove the fill bolt first. Besides having the fluids flow out faster it's better to find out if the fill plug is stuck before draining the transmission / differential..

Dip stick says its full so why does it say it holds close to 11 quarts?

I added a pic of the transmission because it almost the same procedure.

Tools Used
10mm Allen Wrench
Drain pan
Floor jack
Four jack stands or a lift.
Suction Pump/Gun. I bought mine from Advanced Auto for $10.
Harbor Freight has one for $4.99.

Rags
Replacement oil 75W90 about 2 quarts. About 4 quarts for transmission.
Two replacement crush washers.

Update:
Adding the requirements as stated in the 2003 Service Manual
Transmission API GL-4,Viscosity SAE 75W-85
Differential API GL-5, Viscosity SAE 80W-90


Procedure
1. Make sure wheels are blocked.
2. Raise and support car making sure that it is as level as possible.
NOTE: It is better to drain the fluid when it is warm so it flows easier.
3. Use 10mm allen wrench to loosen fill plug (to ensure you can refill the differential before draining old oil).
4. Using 10mm allen wrench, loosen drain plug and allow diff to drain.
5. Wipe off excess oil from drain plug along with fine metal shavings. Remove old crush washer and install new washer.
6. After diff/trans is drained, reinstall drain plug. 23 - 28 ft-lbs for transmission; 55 - 61 ft-lbs for rear diff.
7. Use 10mm allen wrench to remove fill plug.
8. Remove old crush washer and install new washer onto the fill plug.
NOTE: To fill suction gun, I took off the top, pulled handle out of the gun and poured the oil into it. You could stick the hose into the bottle and suction it out but it wont pick up as much.

9. Using suction gun, fill diff/trans to lower level of fill plug and allow overflow of fluid to drain off.
10. Reinstall fill plug. 23 - 28 ft-lbs for transmission; 55 - 61 ft-lbs for rear diff.
11. Double-check all plugs for correct torque (DO NOT OVERTIGHTEN) and wipe off any excess oil.
12. Lower the car.

NOTE: Since you have the car raised it is a good time to change the engine oil, check your tires for feathering, check your exhaust for leaks and bottoming, check your fuel lines for damage and anything else that may look unusual under your car.

Straight answer: no, these are two different and separate components. One sits aft of the engine and the other towards the rear of the Z, between the two rear wheels. Two different types of lubricants are needed and you'll need to use the pump to fill both set of components.
