1. 1

   Check the range button on the T-Lever or Multipad for physical damage, sticking, or accumulated dirt/debris that could jam it in the depressed position.

2. 2

   Disconnect the battery, access the wiring harness beneath the lever, and perform a continuity test on the switch (should be open when released and show continuity when pressed).

3. 3

   Inspect the wiring harness running from the right-hand armrest console to the TRANS module for chafed wires, pinched lines inside the armrest pivot points, or loose/corroded connector pins.

1. 1

   Prep the Machine

   Park the tractor on a level surface, turn off the engine, and disconnect the negative battery terminal to prevent electrical shorts.

2. 2

   Access the Controller

   Remove the plastic trim/covers on the right-hand armrest or side console to expose the base of the T-Lever or Multipad assembly.

3. 3

   Disconnect Wiring

   Locate and disconnect the main electrical connector for the transmission controller lever.

4. 4

   Remove the Assembly

   Remove the mounting screws securing the T-Lever or Multipad to the console.

5. 5

   Replace the Component

   Depending on the specific trim level (Essential, Efficient, or Exclusive), the range button itself may not be serviceable independently. If the switch is integrated and has failed, install a new T-Lever or Multipad assembly.

6. 6

   Reassembly

   Secure the new lever, reconnect the wiring harness, and ensure the wires are routed safely away from any pinch points in the armrest. Reinstall the console covers.

7. 7

   Clear Codes and Test

   Reconnect the battery. Turn the ignition on and use the tractor's onboard diagnostic menu (SIS screen) or a diagnostic tool to clear the 04.X.2B fault code. Start the tractor and test the range shifting to confirm the repair.
