RTV 520 Trans slipping in reverse for about 20 seconds after sitting over night

I have a 2023 RTV 520 165 hrs on it. All fluids filters changed at 55 hrs. Unit has ran great until a few days ago the trans starting slipping in reverse
when i went to back out of garage. It slipped for about 20 seconds then started reversing normally. it ran great all day no more issues
The next morning it did the same thing, foward works and reverse slips 20 seconds , then it acts fine. All fluids are at correct levels.
Anyone have any idea whats going on or have had the same issue?

Kind of sounds like air in the system.

First thing to check is the hydraulic fluid level.

Thanks, Yes ive already checked all fluids and they are at correct levels. I dont see any leaks either.
Guess Ill have to change all filters and fluids and see if that helps
