I doubt if the tightness of the components has anything to do with the jumping of your speedo needle. Its normally due to the long cable catching on a worn spot in the non-replaceable plastic liner. If this is true in your case, you can look forward to changing the whole assembly soon. One thing you might try is to lube the old assembly- something thats virtually never done. Disconnect both ends of the cable. Build a paper funnel and attach it to the dashboard end of the cable with tape. Position it so the funnel is upright. Fill the funnel with motor oil and wait for oil to drain from the other end, under the tranny. Lots of rags at both ends soak up any drips. Let the cable drain from the tranny end, then reattach. This may give you another years' worth of use but eventually you'll need to change everything. Nothing lasts forever...
