Could be engine or transmission mount problem.

Take it to an trusted high rated transmission shop in your area and let them inspect the transmission for a proper diagnostics.

The issue could be anything from a bad transmission mount like mentioned above to maybe a bad shift solenoid located in the valve body or even an bad transmission clutch pack.

All you going to get on this forum with the limited information posted is just a lot of guess work.

Curious... I see that back in March you asked about changing transmission fluid. No mention of transmission problems then. Was the transmission fluid changed? If so, did the transmission problems begin afterward or pre-existing?

I didn't go through with the fluid change as the vehicle got in an accident the following weeks, this problem as already existing but i had no issues shifting so it was weird to me as it only does it sometimes

Sounds about OK 750 being the target.
