probably not, but also not 100% sure. they did make some changes
I could understand the valve body and obviously TECHM but I plan on swapping those over to it so no reprograming is required

Read this if you are swapping 6L80 TCM
Recently I had the transmission in my 2011 Silverado go out. It was slipping the 2-3 and 4-5 Shifts. I took the problem head on, and decided to swap the trans myself and deal with the programming myself. Here's what I've learned. What I did: the 6L80 in my truck was slipping and upon Inspection...
From what I can find the ONLY difference is the TECHM and torque converter. ALL other internal parts are the same (using rock autos parts listing). I plan on rebuild my TECHM and ordering the correct OEM torque converter for my 2011, should be good to go.

The newer transmission will have a thermostat on the side where the remote cooler lines attach. You’ll have to probably put new fittings on the current lines to connect up.
The lines on the 2011 will bolt right up, the transmission cases are the same luckily
this thread ancient, id start another with your specific situation vs performing a necro.
The OP hasn't been on here in at least a year.
In your new post, please give specifics about your year-make-model and the same info about any potential donor parts.
