Appreciate it!
Here is one on the Amsoil website.

Its best to drain the pan and refill before you do the cooler line flush. Least mixing of old and new ATF. (But not required).
Some people can pour in new ATF at the same rate its being pumped out and thus do it in one operation. Needs two people, one to pour and the other to keep an eye on draining the a ATF.
Others drain 2 QTs, stop engine, add 2 QTs, then restart. Best option if you are by yourself.
Some overfill by a QT and then try and drain maybe 3 QTs out before stopping the engine, and refilling.
Hopefully you have some rubber cooler lines and can easily disconnect them (pretty low pressure) and than can attach 4' of 3/8" clear hose going to a clear gallon container (so you can see how much has pumped out).
Best to catch the return so you also flush the cooler.
Throw in a Magnefine filter while you are there.
