cheese burger,

One common problem for a delayed shift is the vacuum line / hose that runs from the intake manifold to the vacuum modulator, unhooked or leaking vacuum.

If there is ATF present inside the line itself, the diaphragm is likely damaged, and will require replacement of the modulator.

This is, of course the "best-case scenario".
Good Luck.
