In search of T87 TCM file with 24283067 os.

Anyone have a T87 TCM file for a 8L90 with the 24283067 operating system. I checked over a dozen files in the repository that could have it but they all have the old 24280476. The updated 24283067 could be in a 2015-17 Escalade or Denali and some Si2015 or newer Silverado/Sierra.

See attached stock file that has the transmission OS you've requested.

Thanks! I really appreciate it. It is interesting that the TSB from GM and TIS2Web show it to correct a harsh 1-2 upshift but the only thing difference I can find is the TCC release in 3rd gear.
