Once in drive 1st gear, are there any concerns with 1st-2nd-3rd-4th or there shifts?

Does this occur every time hot and cold when shifted to drive?

Customer: replied 1 year ago.
Seems to shift up and down through gears fine while driving. When I stop at an intersection I need to rev it a bit to get in gear when it engages it feels solid.It first started in traffic after highway driving (hot) and has done it since. Although I have not driven it much since it started, not wanting to do more damage...

I need an answer to work with, I can't wait 24 hrs for every response.Help?
Expert:  Chris (aka- Moose) replied 1 year ago.

Sorry for the delay, it seems no others here wanted to take a shot at this concern. Since it occurs while still running just coming to a stop, that rules out the converter drain back valve. Since 1st works once engaged I do not suspect a clutch or piston seal issue in the forward clutch. I believe your going to find a lave or spring or bore in the valve body damaged allowing the pressure to the forward clutch to bleed off or delay in getting to the clutch. Do you know how to remove and overhaul a valve body to check it out or rule it out?
