6L90 to 6L80 Express VAN 8.1L E38 2013

[gerbot_4000]

Hello there! How are you doing?
So I changed the transmission hoping to get it working just by changing the VIN... did not work... so after a lot of reading I discovered that I need to find a compatible OS. Either on Chevrolet TIS or a set of Efilive files.

Does anybody have the pair for this combo? Could not find it on the dropbox. I attached the read of the current ECM and TCM modules.

Thanks!2238422385

E38 OS is 12654075
T43 OS is 24270599

Does anybody have a read of the T43 24265260 OS?

Thanks again!

you went from a 2013 6l90 to 6l80 wich year? did you tried it with the vin that was on the 6l80? It should talk if it from a similar year, 2011 plus. what troublecodes?

Yes 6L90 2013 to 6L80 2016 I think. Yes changed the VIN. But has different OS not compatible with the ECM.

Only code is lost communication with ECM.
There is a list that EFILIVE is compatible with 24265260 OS so I guess they have a reading of one. So it would be awesome if someone has a reading of that OS as I already used the cr

I have this OS, and a few different OE cals. PM me if you still need it. Also 24265260 is not compatible with any other OS... -_-
