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.
