You go-fast wannabe.

OK, I remembered where I may have picked up the wrong info. Way back in 2007 when I was getting the my deep transmission pan and TransGo shift kit installed, my mechanic mentioned to me that he had a bit of a problem because the shift kit was really for a 4L60 but I had a 4L65 with a couple of small differences.
Now in my Helms manual, they actually list 3 transmissions in 2006:
4L60-E
4L65-E
4L70-E
WIth associated RPO code of M30 - M32 - M70. I will check in the glove box to see what it says.
However,
this page clearly indicates that in 2006, the 4.2 and 5.3 engines got the 4L60-E, and that the 6.0 (SS) engine got the 4L70-E (not not the 4L65-E). So why are all 3 versions listed in my Helms manual?
BTW, there is some good information in the documents on that page as to what the differences are between transmissions.
