You will absolutely not be able to use a 2007 TEHCM in a 2012. The TEHCM has to be correct for the year and the valve body has to match the TEHCM. You need to use the entire 2012 valve body and TEHCM in your 2007 transmission but swap the speed sensors from the 2007 valve body. Since it’s already programmed to your truck, it’ll work without programming but you do need to reset the shift adapts pretty quickly.

Ok that's what the Facebook responses were saying, but they didn't mention the sensors or anything. The speed sensors are both pieces with wires? So take those from the 2007 valve body and put them on the 2012 valve body. Then put the 2012 valve body with 07 sensors into the 07 transmission? I think I got it. Thanks everyone

Let us know if this works. I'm not sure about running a 2010+ valve body/tehcm on a 2006-2009 case in a 2010+ as I've never done it. But the case components themselves never changedso maybe it will fly.

All the 6l80e are the same i think all the way up to 2014 even from newer trucks with the lt1.

The cases, most of the case internals are either the same or immaterially different. Valve bodies and spacer plates are definitely not all the same. 2010 saw a redesign of the vb and plate; 2014 saw the introduction of a new spacer plate with an 8th checkball (2006-14 had 7 check balls). You can retro an 8th check ball in all VBs back to 2010 if you install the 2014+ plate.

Update. Zero issues, been driving it for a week. Knock on wood this lasts till I get the original rebuilt.

Thanks everyone
Great news, @jrobie79.So the VBs are interchangeable as an entire assembly provided the TEHCMs are either fast-adapted, reprogrammed if necessary or a 'correct' TEHCM for the vehicle is installed (the TEHCMs themselves never changed structurally, just programming-wise)...Haven't tried swapping across vintages for obvious reasons but now I know it will work if performed.

Thank you for following up.

We should invite @NickTransmissions into this discussion thread. If my memory serves me well (less and less each day), Nick had stated that the 07 and 08 transmissions are different than the later GMT900 models and are not fully compatible.
have a 2007 cadillac escalade with the 6l80. I bought a 2011 chevy tahoe 6l80 both transmissions are 4x4 tail housing. What im wanting to do is put the 2011 transmission into my 2007. I have read its the same transmission, and I should just have to put the tcm and valve body out of the 2007 into the 2011? Or can I just put the 2011 transmission into my 2007 with no parts swap and just bring it to my tuner and have him flash the tcm?

Please Let me know

This escalade has been swapped with a Corvette LS3 on stage 3 came and ton of engine work and we roasted the 2007 transmission being awd. Now we are doing new trans and gonna do a 4x4 transfer case to get 2wd and only 4x4 when we want it

Can somebody tag @NickTransmissions for some reason it wont let me

Nick does not accept PM's, and for good reason. Tagging him in the open thread is the only to get his attention and potential response.

Not sure if you have solved for the above but you can install the 2011 unit and either program the TEHCM to the vehicle or swap over the 2007's TEHCM-VB assembly and then run a fast adapt relearn before driving it.
