aod problem

i just finished overhauling aod tranny when engine is first started and cold shifts great after its warm will not shift out of 1st until about 5000 rpms doesnt seem to slip just wont shift i also added transgo shift kit at overhaul and the hirev kit any ideas please help trans guys[img]/phpBB/images/smiles/icon_confused.gif[/img]

Since it shifts but delayed it's either a jammed govenor (tailshaft) or you have a valve binding in the VB since the shift kit was put it.

Take out the VB and go through it carefully one more time.

Not much else it can be.

thanks for advise i have also noticed something else when trans is getting to point it isnt going to shift the line pressure goes very high. i can drive it about one mile before it starts to acting up like i said before it starts to act up it shifts into all gears very well also found when it doing this it will not downshift when i put shifter in lower position[img]/phpBB/images/smiles/icon_confused.gif[/img]
