Default Transmission Problem??

I have a 2017 GS A8, stock with almost 30k miles on it. I keep having an inconsistent shift problem. Sometimes when I shift from park to reverse or reverse to drive, I get a 2 second hesitation or delay before the transmission changes gears. I'm wondering what could be causing this as it doesn't happen every time, just once in awhile. I'm wondering if this could be an upcoming transmission problem or if there's some kind of sensor that's faulty. Has anyone had this problem before? Thoughts on what could be the cause? Thanks

I have this problem as well, especially on cold starts. Got a transmission flush and filter 6 months ago .

Have you done the triple flush on your transmission?

This is a problem with the Auto 8 transmission for 2015 through 2019 cars. See the "permanent sticky" on this forum for lots of discussions on this issue.

A Trans Relearn with a tool like HP Tuners resolves the issue. I have to do it every year on my 2015.

Clear Adapts and perform a Garage Relearn , then when uts is relarn mode ( 100 miles ) drive it like you stole it

Any competent shop as the ability

Fluid has nothing to do with sloppy or slow shifts
