Needing a little help figuring out why I cant get different shift modes, or at least insight on perhaps it doesn't exist on this OS.
On my Lincoln everything works perfect, in drive normal shift pattern. Pull it down one selection and it goes into the performance shift pattern.
Now on my 08 Envoy I have swapped to a 6L80 using a 2008 Escalade trans and OS. I did have to do a segment swap to get my PRNDL and Speedometer to work correctly, but those came from my friends 2009 T43 in his 9-7X that also came from a truck application.
As far as performance mode, I can not seem to get this function to even show up on the scanner. I have changed the shift schedule drastically enough that it would be obvious as soon as you pulled it down a gear.
The one weird thing is when I do pull it down say around 55-65 it does downshift into 4th almost like it goes to a tow haul mode.
In my log you can see at 30 seconds in where I pull it down, also at 52 seconds I bump it back up into drive.
