My understanding is the software is out for the 6spd Allison now. If there is anyone in the Houston area willing to recalibrate my speedo and shift points please contact me. Thanks in advance...:D

Speedo recalculation is done in the ECM not the TCM.

When I was living in New Orleans a service tech there tried, but when he tried to adjust the shift points, he was unable to communicate with the TCM. He called me and said it was out now, but I have since moved back to Houston. I have zero knowledge of this software, so please don't think I am questioning your knowledge on this.

your speedo is set in the ECM (engine control module)

shift points are set in the the TCM (trans control module) witch just came out this week.
