Issue
Getting consistent shift pressures has been difficult. Shift errors show false numbers of 6.xx seconds and it bumps up the adaptive pressures causing very harsh shifts. Also tow haul mode no longer works, i believe it was working at some point after the swap, however I noticed the other day when i tried to change the shift points it does nothing. Dash light comes on but no change in trans settings occurs.

Unexplained Scanner Values
Trans Shift Mode: Unknown 0B - there is little info out there on the meaning of this.
ETC Torque Management Type: Unknown - 1a 00 2a 3f 3X XX XX XX constantly changes with rpm but I also don't know the meaning of this.
