A 2000 Jeep does not have a torque converter drain plug.

No
The 2000 Chevrolet Tahoe 5.7 liter engine oil drain plug is a 9/16 drain plug. The oil drain plug has very fine threads.
There is a pitcock valve on the bottom of the radiato. On the side facing the engine. It has a T shaped handle that you can unscrew to drain the radiator, and by default the engine block. You may have to use pliers to unscrew the plug, over time dirt and corrosion can make it dificult to loosen.
Use a quarter drive socket handle, insert and turn a quarter turn. Do not force. Check out pix at http://99intrigue.shutterfly.com/headgasket/115. Go through the next four or so pix on that page. Of course, this is the radiator drain plug. If you cant do the oil pan plug, you might not want to be working on your car.
The drain plug is no the lower left hand side ( driver side ) of the radiator.
It should be on the drain plug.
If you are standing in front of the car. It is underneath of the drivers side.So you have to replace drain plug from under car.
Bottom of the oil pan.
The drain plug is just below the lower radiator hose.
