94Z just approaching 93k with an auto transmission.

It was hesitating on the 1-2 shift and the 2-3 shift this afternoon. Goes into gear fine from Park or neutral. Fluid is fine and not discolored/burnt. I do have a tranny cooler as well to keep it cool as possible. Later in the day I drove it again and it was fine. No error codes or idiot lights on, engine is fine.

Planning to drop the pan and change the fluid and filter soon, will see if anything is in the bottom.

I realize it will need a rebuild eventually, but didn't want to do it quite yet.

Let me know if you have any ideas or other things I can check.
