Not with GM SPS, don't know about other software.Originally Posted by Jeff Fro

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.

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.
Visiting this page, I see a plethora of products. Could you be more specific of the device(s) one needs to accomplish the initial flashing of a TECM?
Appreciate ya.
Use your HP Tuner dongle and HP Tuners. It will flash the TECM. I use SPS but many have used HP.
As a side note I have off board programmed several TECM's with SPS/TechLine Connect
To be clear, if I scan my current 6L80 with my HPT, then I should be able to program the new rebuilt 6L80 from GM?
IT DEPENDS! There is no way for you or me or anybody anywhere to say whether it'll be a new-new totally blank TEHCM that HP Tuners can't detect, or if it'll be a reman TEHCM that's already had a cal put in it at some point and is detectable by HPT. Maybe the totally-blank thing was something they only sent out like that for a while but now they all have some generic placeholder cal in place, or maybe the new-new TEHCMs are still like that. If HPT won't detect it then it will have to be flashed the first time with SPS and you won't know until you plug into it and see what happens.
