Hey Fred,
The 904 ratios are too close together to take much advantage of splitting, but more importantly, I was told by GV that you cant have the power going into the unit on the outshift. That is to say you can put full power into it on the upshifts; as in from first into 1-od or from second into 2-od. But when going from 1-od into second, the power has to be interrupted until the box has outshifted. And as you have discovered,. that vcontrol module has a time-delay in it, so that really sucks.
To be continued
