E92 Not being supported yet?

[05gmcsierra]

I pulled the E92 file from a 2014 silverado but i cant open it on 7.5 .. it says

This version of the EFILive Tuning Tool has not been
configured to display this PCM's operating system.

and while im here i tried pulling T76 transmission file but it said that it was locked and i wasnt able to pull it from the truck has anyone else ran into this problem?

TCM would have been a T43 in that, the T76 is used in GM's FWD applications.
