You may have to do this a couple of times, but I think not. I think once you get
most the gunk out, and clean it, the new fluid should flush it out. Try it, and
if
it works, it will save you pulling the transmission apart. If it doesn't, then
all
you are out of is some time, fluid and a gasket kit. Just don't run it long if
it
does act up again.
