That is typical of some of the older trannys. Same thing happened on
my 79. Seals start to harden and there is some wear and leakage so it
takes a minute or so to warm things up to provide a better seal. Had
to start mine and put it in reverse to back out of garage but hold
brake while I put on seat belt, etc. In a short bit of time I would
feel it start to pull and away we would go.

There are some additives that you can add that are specifically for
that problem that contain chemicals that will swell the seals. Only
problem is that they also soften them enough that they wear more,
faster. That means a rebuild is near.

Good Luck
