speedometer sensor

  1. #1
    Speedometer seems to stick at 55mph even though brakes have been applied, then needle will eventually drop back down again.
    I am looking for the sensor which is located on the transmission housing, next to inner end of the right hand driveshaft, according to haynes manual.
    I cant seem to find it.
    Is the right hand driveshaft on the passenger or driver side, so I can stop wasting time looking.
    If of any help it is a vtr gearbox Mk1.
    Any help appreciated
