If the trans is a six speed, the five speed sensor will not work properly. PN for he five speed sensor is 74430-00D and PN for the six speed sensor is 74402-05. If the trans is a HD trans, the speed sensor is in a completely different location than on the early models. If an aftermarket six speed, like Baker, Ultima, Rivera, etc, the trans and/or gear set will come with a new speed sensor to replace the OEM sensor.
