I am assuming you mean it is not upshifting as opposed to
going to "nuetral" in which case you have an entirely
different problem. If it is a 3 speed, you may have a stuck
road speed governor. It is located in the tailshaft
housing. IIRC, it can be service (unstuck) by removing the
ts housing. It is not a 10 minute job, but, it is not too
bad or complicated if you have a few tools and are willing
to learn as you go. You might also want to check your
kickdown to be sure it is not stuck at full throttle
position for some reason.
