10l80 fluid and filter change procedure

[Ronjon]

Hey guys, I have a 2020 Silverado 3.0l Duramax. I'm looking for the gm filling procedure. I wasn't able to find it and was going to try a local dealership for it if this doesn't pan out.

 

I know the temp needs to be brought up and gears cycled through, but I was hoping for an official document for it.

 

If anyone has it I'd appreciate it.

Just following up for anyone interested. PPe emailed me back recommending @DemonWorks's videos on it. He's also posted a follow up going over missed details and procedures. I'll be doing the install next month along with a filter replacement.
