Default 4L65E Identification-Confused

So I purchased what I thought was a 4L65E core to rebuild for a LS swap I'm currently doing. I was told it came from a 2005 Hummer H2. I assumed it was legit because if I'm decoding the case decal correctly (6KZD) that would be a 2006 H2 correct? Anyway, I tore it down today expecting to find 5 pinion gears but both were only 4. Now I'm wondering what I really have. It does have 7 frictions in the 3-4 clutch. I was hoping to have the 5 pinion gears (although I know the 4 are probably just as good). However, I was also hoping for the hardened input shaft. Is there a way to know what I have here and if I at least ended up with the hardened input shaft?

A couple points here. 4 pinion planets are NOT a weak point of this trans. The 5 pinion is not something worth time, energy, or money searching for or worrying about.
As for the input shaft...post a picture.
The rest of the trans...doesn't really matter. You'll be changing things to get it setup properly for your usage anyway so it won't matter.
