Position Sensor
Illustration 4 g00348078
The transmission lever position sensor (1) tells the transmission control the speed position of the shift lever. The shift lever is controlled by the operator. The transmission lever position sensor is connected mechanically to the shift console.The other position sensor (2) indicates the speed that is engaged. This position sensor is connected mechanically to the rotary actuator of the transmission hydraulic control.Except for the different pin numbers at the switch, both position sensors operate similarly. Each sensor is mechanically positioned with diodes that determine current flow.Neutral Start Control
The neutral start control operates in order to ensure that the machine will only start in NEUTRAL. The control gets a signal from the shift lever switch. When the switch lever is in NEUTRAL, the signal is grounded and the machine will start. If the shift lever switch is not in NEUTRAL, the ground is broken and the machine will not start. This will prevent the machine from being started in gear. The neutral start control is located in the shift lever console.Note: For more information about the electrical system operation, refer to Service Manual, SENR6829, "Electronic Programmable Transmission Control (EPTC-II) For ICM Transmissions" .
