I think the shudder problem between gears is likely to be bad timing of the handoff between the two clutches. If this is the case it could be the mechanical linkage in the actuators is bent/too-long/too-short/etc so that this messes with the timing of the handoff.

What would be nice is a user set of timing offsets to adjust things. I have to believe Ford engineering has such tools and it may well be they know what the problem is and have decided to do nothing to fix it.
