I'd say that with the 4.88 gear the speedo was disconnected.
Also if the tranny is not original, the new tranny may not have the correct cable or gear for the speedo to read correctly.
Another thing is that the back of the speedo cluster may have a date.
If the date is off it could have been replaced.
