Cvt color should be very clear with a slight yellowish tint. Does it shudder real bad, but above 5 to 7 mph smooth out and drive normally, or does it shudder at any speed? If it is a cv joint I would think it would be more noticeable with the wheels turned left or right. Yes you fill it through the dipstick hole, and the sin is about where you indicated. I believe that the drain plug takes a 1/2 inch breaker bar square drive, i.e. your breaker bar will fit right into it.
Check the color and level of your fluid, if not correct, drain and check for stuff in the fluid. Lots of times places top off the fluid with normal trans fluid which makes it shudder very quickly. Normal trans fluid will make the fluid color red or brown. Only use the real Honda cvt fluid.
