Are you getting a check engine light? Are all fuses good? Any more information you can give us will help solve your problem. Please advise.

If driving and driven gears are both good, It is probably the vehicle speed sensor. You should be able to verify this with a computer diagnostic unit with vehicle either running on blocks or doen the road. If VSS checks good, it must be the speedo head itself.
