If you have a lift it is easy, if not it might be a PITA. There is a little filler plug on the side that you use. If you did it at 64K and you now have 92K I think you can surely wait.
Does the car need to be running when I check the level? I pulled the plug on the pass side and fluid came out. The car was cold and the pass side was jacked up?
In all honesty, there is no real way to check the fluid, the dumbest design on these cars. If you changed it at 64,xxx, I wouldn't even worry about changing it with the miles you have on it now.
