All,

I had no luck searching, but in the driver demand increasing and decreasing tables (with 8L90E trans in 2018 Sierra) it lists gears 0-9.

I am trying to figure out how they translate to the actual gear. I swore I saw this somewhere a while back, but I can't find it again.

My assumptions, and likely wrong, are:

0 = neutral/park
1-8 = corresponding gear
9 = reverse

Thanks.
