Why would you pour trans fluid (basically oil) into the cylinder? That would cause the spark plugs to foul.

If it's worth your while to wade through 2 pages of back-and-forth troubleshooting, see the old Narrowing down the problems to a broken bike thread.

In one of the posts I linked to a couple of older threads that no longer exist.  Fortunately, I included the relevant parts of those threads in a later post.  Anyway, if you can make it to the bottom of the second page and fill out the checklist, that would be a great help in diagnosing your problem.
