Hi, I located the tcu on this 2019 Sierra but I cannot tell if it's supported as it doesn't look like any of the T87 units.
Pictures not working but part numbers on this tcu are:
812928414
84655238
1119053000000552
Can anyone confirm? Thanks

Not supported.
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.
Darn, thanks for the info though.
