I have a 2011 6L90 VIN 1GT21ZCG1BZ262207 OS 24256125 Cal. 24256939
This Trans was paired with a e78. I would like to pair it with a 2011 LY6 and a e38.
My Question is what Trans OS would be compatable with the E38 or will the os thats in the trans. now work with a E38 with out a reflash.

I can't say with 100% certainty, but the TCM is probably not going to be too fussed what ECM it is, as long as they are from the same year model the TCM will still happily talk to an E38 or E78.
