| B315A Transmission Range Control Valve 1 Position Switch | A linear hall effect sensor that changes current flow based on the magnetic field's position relative to the sensor. |
| K71 Transmission Control Module | The control module contains a microprocessor used to process input data to control outputs.The control module receives information from a variety of sensors, switches and serial data information from other control modules. This information is used to control a combination of solenoid valves to obtain the correct line pressure, gear ratio and torque converter clutch operation. |
The B315A Transmission Range Control Valve 1 Position Switch monitors the position of the Mode 1 Electronic Transmission Range Selector Valve
- Default = Low Voltage - 0.6 to 1.0 V
- Active = High Voltage - 1.7 to 2.2 V
