1. 1

   Use a voltmeter to verify the supply voltage to the transmission module, as low voltage is a common cause for module faults.

2. 2

   Visually inspect the module's connectors (often located below the console) to ensure terminals are completely inserted into the housing and no terminals are exposed.

3. 3

   Check if the locking tangs on the terminals are damaged, which can cause the terminal to back out and lose connection.

4. 4

   Check for CAN network initialization errors or interrupted signals from the Autotronic transmission controller, which can mimic a dead module.

1. 1

   Access the Module

   Locate the transmission module. Depending on the model, this may require removing the outside cover panels of the side console or accessing the electronics box.

2. 2

   Remove the Module

   Disconnect the battery isolator/ground. Carefully unplug the harness connectors from the transmission module, ensuring you do not damage the locking tangs. Remove the mounting hardware and extract the module.

3. 3

   Install the Replacement

   Mount the new or remanufactured transmission module and securely reconnect the wiring harnesses.

4. 4

   Calibration and Programming

   A new transmission module will require programming and calibration using a specialized dealer diagnostic tool (like the electronic service tool or Wintest software). You must calibrate the transmission parameters, drive pedal, and clutch pedal.

5. 5

   Clear Codes

   Clear the stored DTCs from the system and test drive the tractor to ensure range changes and transmission functions operate correctly.
