Re: spedometter part? what is it

If this part was installed on your vehicle from the factory then yes you do need it to make sure your speedo reads correctly as it is a gear reduction unit for the speedometer. the drive gear on the tailshaft of the tranny and the driven gear in the tailshaft housing are geared as closely as possible to your given speedo but not quite good enough for a really accurate reading. This reducer helps correct that problem.
