| Component |
Description |
| B14D Transmission Intermediate Shaft Speed Sensor |
The sensor contains a hall-effect sensor and additional electronics that processes the signal. It detects the change of strength of the magnetic field caused by the reluctor ring. When the strength changes, the sensor changes the amount of current it consumes. This results in a square wave signal of the current, while the voltage stays constant. The control module detects the frequency in which the current changes, which is proportional to the rotational speed. The sensor is an input to the control module K71. The input signal is used to determine the rotational speed of the component: Reaction Carrier Assembly |
| 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. |
| Reluctor Ring |
The reluctor ring is part of the component: Reaction Carrier Assembly |
