Cold 727 slipping. Any ideas?

I left for work and had to back up my driveway which is inclined. Transmission slipped some. Got to a steep hill at a stop sign. Called rolled back when I tried to pull out. Hit gas hard and it chirped tires and went on.

Fluid level is good. I have been letting it sit in neutral a few minutes before I leave and that seems to help.

No problems once it’s ran a few miles.

rebuild time?
