Can a 2008 G8 be re-programmed to a 2014 truck trans?

Can a 2008 G8 be re-programmed to a 2014 truck trans?

Not with GM SPS, don't know about other software.

You will not be able to program the 2013 as a 2008. They are different enough that SPS will not allow it.

What if I overwrite the 2013s transmission flash code with the one from the 2008s transmission? Can I use the MPV12+ and VCM Editor to download the tcm flash from the 08 and upload it onto the 2013?

If the Service Numbers interchange, go for it. But you can't just go doing stuff like that without verifying interchange first.

How do I verify that the service numbers interchange? Where are the service numbers located? What do the service number indicate? What are service numbers? Did I mention I am new to electronic transmissions?

The Service Number is like a part number, but is for the hardware only, it does not describe anything about what software/calibration is in it. A Part Number on the other hand is a specific Service Number with a specific calibration in it, that would be a direct install-and-go deal for a specific vehicle. Once the cars/trucks are more than a few years old you can't buy a bolt-in preprogrammed Part Number replacement anymore, you just get the basic compatible hardware and program it to the application. That way they can have one part on the shelf that 'fits' many many different apps.

2008 Yukon 6.2 TCM: 24275872 https://www.rockauto.com/en/catalog/...nit+(tcu),8480
2013 Yukon 6.2 TCM: 24275873 https://www.rockauto.com/en/catalog/...nit+(tcu),8480

Would appear there is an incompatibility between them, else they would have obsoleted one and replaced it with the other. Both are current numbers.

And with that the purchase is canceled. Thank you Mr. Squirrel for spelling that out so eloquently.
