ABSTRACT:
An electronic communication wire connecting an input speed sensor and a computer controller in a transmission system is provided. The electronic communication wire connects at one end to the input speed sensor through a first aperture in the transmission case and at the other end to the computer controller through a second aperture in the transmission case. Thus, the electronic communication wire is attached at both ends to internal devices but it partially exists external to the transmission case along the length of the electronic communication wire. The connection between the electronic communication wire and the input speed sensor is sealed with at least a single O-ring while the connection between the electronic communication wire and the computer controller is sealed with at least a pair of O-rings. A method of electronically connecting the input speed sensor and the computer controller externally of the transmission case is also provided.
