The cable could be gummed up inside the housing. Disconnect the end from either the speedo or trans, pull the cable out, clean it real well with brake cleaner, lube it up with a graphite based speedo lube, slide the cable back in, and hook it up. Check to see if the cable is frayed at all while it's out too.

You will need to change the drive gear in the tranny to correct your mph problem if you switched rear end gears. Wont help the jumping problem though.
