Can you drain the oil out and see if signs of glitter of metal disintegration

Did you try to change the gearbox liquid brand and put the correct volume in it? Check the overflow valve up ahead the gearbox to be free and moving slightly. Is important when hot liquid expands. Or leave the fluid stick checker a bit loose out and see if it changes.
