Lagging when shifting?? (727 auto, w/ full manual valve body)
What is probably the issue is that either the direct clutchpack has a leak in it, a possible broken sealing ring on the pump stator, or low pressure (Like a failing pump)
Could be a broken spring on the pressure regulator valve (Pretty rare though)
A pressure test is in order.
PS, you might want to be really easy on it till it gets figured out because those real slow shifts are pretty hard on clutch material.
Huh, now I'm even more confused lol!! I was told there was a full manual valve body on it, and it DOES shift by itself...... So I'm guessing that means I don't have one?
