| B15 Transmission Internal Mode Switch |
The switch has 5 contacts which close in a specific sequence depending on the position of the selector lever. An additional contact generates a P/N signal for the engine control module. |
| 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. |
| K20 Engine Control Module |
The control module contains a microprocessor used to process input data to control outputs. The control module controls a series of actuators to ensure optimal engine performance. The control module does this by reading values from a variety of sensors, interprets the data and adjusts the engine actuators accordingly. |
