It just sits there, then engages and off I go.
I take my foot off the brake and it may or may not move. Eventually it
will. Sometimes a quick blip of the accelerator will get it to move
other times, I have to wait for it, the apply throttle.

When was the last time the fluid and filter were changed?

Dumb question, but gotta ask... have you checked the fluid level, with the
engine running and tranny in neutral? If that's OK, then removing and
inspecting the pan will tell you whether it's a repair or a re-build.

Yep, fluid is full to the mark. I check it warm, after a nice long
drive, and then in neutral.
I last changed it 2-3 years ago ....maybe 25k miles. I'd have to check
my maint log. I was changing it every year myself.

It could be a weak main pump or leaking seal on clutch pack. As idle
oil flow is at it lowest and leakage would cause the most trouble.
Since it graps when RPM increases it tends to suggest a weak pump of
clutch leak because oil flow would increase with RPM and overcome a
leak or weak pump. If this is true it would also tend to maybe slip
more when it is fully hots and do its best when it is between cold and
fully hot.

Seals or sealing rings in the rear clutch are shot.
