Jeff's 727 rebuild thread

I have a question about the 1-2 up-shift...
Under WOT or even light throttle it seems to shift from 1st to 2nd VERY soon.....15 MPH tops....even under WOT.....It doesn't seem to spend very much time in 1st gear.....and of course, that doesn't let me get the RPMs up where I'm making power...
Is this normal?
I don't want it winding up real high in 1st under normal driving conditions, but when I punch it, I'd like to stay in first a little longer.
Is this a throttle pressure adjustment issue or ?????
