Is a torque convertor the same as a transfer case?
I have a 2000 4x4 Expi and am wondering if the transfer case has fluid separate from the transmision that needs to be changed. I have the 5.4l and the larger transmission.

Yes, they are separate. I change both at the same time but others do not. Both the transfer case and the transmission use the same type fluid.

"Stuff you'll need:
2 quarts of your favorite ATF
drain pan for the old fluid
Some towels for cleaning up
10 mm allen socket
a smallish funnel
Find the transfer case. The drain and fill plugs are towards the rear. The drain plug is the lower plug. The fill plug is the upper plug.
Put the drain pan under the transfer case about where you think the fluid is going to go when it arcs through the air. The 15-quart pan that I use for the oil works well here, and I rarely loose any ATF.
Use the 10 mm allen socket to loosen and remove the lower, or drain, plug. You can do the last few turns by hand. Move the drain pan to where the ATF actually arcs. Then use one of the towels to wipe off your hands.
In a few minutes, the flow is about finished, though it will trickle out the last spoonfull over the next three hours. When you've had enough, replace the drain plug.
Remove the upper, or fill, plug.
Add two quarts of ATF using the funnel. There exist small pumps at NAPA that make this part of the job really easy.
Replace the fill plug, and you're done. I take the used ATF back to AutoZone.
Notes:
1) There has been some discusison in this forum indicating that the transfer case will hold more than 2 quarts, but you have to raise one side of the truck to get the additional fluid in. I don't do that.
2) I like to use a towel to make a dam on the protective cross-member to prevent the last half-pint of ATF from oozing all over the top of the cross-member.
3) The transfer case is really close to the exhaust pipe which can be uncomfortably hot at times. I prefer to change the fluid in the tansfer case about a hour or so after shutting-off the truck."
