Quick question I’m trying to do a 6l80e swap in my truck how ever I can only flash it from an early year OS tcm. From 07-08ish escalde or Denali wondering is there a way anyone could tell me if the tcms are the same or compatible? I read everywhere that GM changed the software from 09+ so I can’t swap those trans in my 08 Silverado. I already have the g8 trans sitting in my garage just want to make sure the OS as stated is compatible with early years 6l80e. Thanks in advance sorry for making things complicated
