2004.5 FMVB During the 1-2 shift trucks shuts off while throttle is still applied.

During the 1-2 shift the High-speed governor goes to 0mm3. The FCA DC % goes to 1,600. Once the Uncompensated MM3 goes to 0 the truck turns back on. You can see the throttle position stays the same as this happens. Anyone ever seen this before?Attachment 139049
