Need info on a 6l90 trans

[chevyguy_72]

I am looking at ordering a new 6l90 trans from GM...
Prob is they have literally about 30 part numbers for 6L90 transmissions ranging from 2009-present year and ranging from Truck, van, Camaro ZL1, CTS-v, Avalanche, etc as far as what they are out of...
I like the truck ones because they still have the slip shaft output shaft similar to turbo 400 etc... the camaro ones have a solid output shaft and you have to get a drive shaft with the slip shaft built in (Similar to Hart Rod) also there is a difference in the oil pan (height/capacity) but those seem to be interchangable...

I am trying to research the differences from there... the only thing i or the dealer has found is that the valve body seems to be a different part number from the truck vs ZL1/CTS-V Trans...

Anyone else might have any input or some solid places to look for info?
Thanks
