This is the procedure I used, which I confirmed is the same procedure, word for word, from the AllData repair manual:

FYI, AllData is a site that independent shops subscribe to. The information is populated from the OEMs to generate a database for performing repairs. This is why your independent oil shops can change the oil in your car.

One thing I noticed in the procedure is raising the vehicle on a hoist. Does keeping the vehicle perfectly level have a huge impact? Obviously this would be difficult to do on ramps or jacks in the front unless I'll need to also raise the rear...

The level plug depends on the trans being level, or else you might drain out too much/not enough. You don't have to have a lift though. If I didn't have that available, I would measure the fender height, pull the wheel, and when doing the level plug adjustment, lower the jack down to that fender height measurement. The plug is easy to get to with the wheel off.

I'm not sure of the procedure differences and what benefits the dealer has over this. Supposedly it gets out more fluid, but idk. I ran mine through the gears on the lift and let things work through, so I think I got a good amount replaced.
