Good evening... Just swapped an '18 L86 from an Escalade mated to a '17 6L80 from a silverado and need a factory 6.2/6L80 file to flash in this E92A. Obviously the stock ECM is an 8spd file. Can anyone help? Thank you kindly in advance.

That file won't exist.
2014 was the only year that the 6.2 came with a 6L80e to my knowledge and that was only in the half ton trucks. All the SUV's got the 8 speed with the 6.2.
Anything after 2015 was 6.2/8L90e and the 6L80e was the V6 and 5.3 only.
I suppose you could write the computer with a GM tool to a 5.3/6L80e file from 2017-2018 and then just change the engine side of the calibration for the 6.2 engine you are running. Never tried it but I'd think it would work.
2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.
If you don't post your tune and logs when you have questions you aren't helping yourself.
The 6 speed is used up until 2018, that's why I said it came with the 4.3 and 5.3 engines.
The 6 speed was not offered with the 6.2 past 2015, so a 2017+ file that is a 6.2/6L80e combo does not exist.

5FDP is correct that, "The 6 speed was not offered with the 6.2 past 2015, so a 2017+ file that is a 6.2/6L80e combo does not exist."
The 6L80E was offered in the next style 2015 SUVs behind the L86 until 2015.5 when they all received the 8L90E. I have several files from late 2014 production 2015 Yukon Denalis with the 6 speed behind the 6.2. But that does not matter as my files cannot be written to an 17 or 18 "a" module.
The 6L80E in the 2015 had the TCM in the trans (controlled directly by the E92) just like a 2007 6 speed (internal TCM) was directly controlled by the PCM...so there is no chance that a 2017 L86 E92A/T87A programming will control a 6 speed internal mounted TCM.
The only chance would be to rewire your harness to mirror a 2017 L83/6 speed then put an OS from an L83/6speed into the E92A and copy the L86 info to it. That should work fine.
The ECM and TCM is separate. Leave the ECM 6.2L tune alone and flash a 15+ 6L80E OS into the TCM then read it all back out.

Your 17 6L80E already has a compatible calibration in it as it is from a Silverado. As long as it is wired to the E92A properly (no T87A), you can read it and tune it now.
