Per information I've found, here is one procedure apparently from Manny T.

An easy way to calibrate the dip stick without removing the pan is :
Take the GMC out for a drive to get the oil hot and the torque
converter full of oil.

Remove the vacuum modulator and fill the tranny until the oil just
drips out of the hole from the vacuum modulator now mark your dip
stick at the full line.

Question I have is: What temperature should the oil be for this to
be accurate??? There is a huge difference when the oil is 140 degrees
vs 200 degrees. And how much time would I have to do this before all
of the oil drains back out of the converter??

Thanks
