6l80/90 4WD VSS
Is the VSS internal to the 6l80/90's in the 4wd trucks like the 2wd units?
The Gen III trucks have the VSS in the transfer case with a 4low switch to the PCM to tell the trucks in 4low.
If the VSS is in the trans how does the truck know it's in 4low?
And does it change anything in the tune when it goes in for low ie shift tables?
