Regarding any difficulties finding neutral, some people seem to have this problem, but I honestly
don't have this problem myself. However, I certainly have discovered that shifting into neutral
can become more difficult
if I overfill the oil level. My transmission shifts easily into neutral, even with the engine running, as long as I don't exceed the 1.7 quarts of engine oil recommended by CSC.
Shifting into neutral can become more difficult if you add excess engine oil, which raises the oil level greatly above the midpoint of the oil inspection window.
The NC250 engine employs a so-called, dry sump system, which is explained post #1 of the following thread.

Therefore, it is important to check the oil level using the proper method recommended by CSC, which is also explained in post #4 of the thread linked above. Adding excess oil will exacerbate any problems one might have while shifting into neutral.
