I am having some transmission problems with shifting on my 450f. I was looking at the service manual and it seems very complex to get to the shift forks and gears (where I beleive my problem is). I have never split the cases on this motor before. I am very mechanically inclined (or so I believe), just wondering how big of a task this really is going to be. The manual calls for all sorts of special tools to do the job. Am I going to need some, if not all of these tools to do the job right? When I shift from 1st to 2nd, I seem to hit neutral a lot, and shifting in general is not as smooth as it used to be. My belief is that one of the shift forks might be damaged. Any other input would be awesome.
