AT TSBs in 2019?

Does anyone know if the 2019s come with the latest TSBs for the AT? Has anyone asked to get one done?

 

Wondering the same thing myself. I've had mine for maybe 4 weeks now and the transmission studder/shudder/limp dicking is getting on my nerves. I have tried to see if it's brakes or transmission and cannot come up with a solid conclusion. It does seem to be better in ECT power mode, but that could be my imagination. It's only when driving around town, light to light that I notice it. And only recently that I take my kid to baseball practice where that's the case. I've really been considering the OV Tune.

 

Fuck it, just bought the OV tune. There's a promotion that lasts until the end of the month, $92 off. I'll report back with my findings.

My previous truck was an 04 Chevy Z71 and it was crap until I ran a Diablo tune on it. The biggest fix it did was resolve the shift points. First gear in a Chevy was so long it seemed like my house all the way to the interstate.
