Wonder if that is part of the problem.
Does torque converter fill up when running?
Drain back down into the pan when not?
Could account for your discrepency.
Never really thought about any of this till now.

I actually started with a cold engine and trans. I had check fluid levels the night before after I had drove the Jeep and it was still hot. Once I drained and refilled I drove the Jeep for about 2 miles getting up to 45mph. Each and every time I drained the pan I got the exact same amount of fluid. Of course, just for clarification, the Jeep was not running when draining the pan and I had let it sit for five minutes before draining.
