1. 1

   Verify transmission oil temperature is between 35°C (95°F) and 45°C (113°F) on the Dash Control Center under diagnostic screen 1

2. 2

   Cycle the PowerShuttle lever (forward and reverse) 10 times in each direction for 5 to 10 seconds to warm up components to the exact temperature of the transmission fluid

3. 3

   Configure the PowerShuttle progressivity settings (forward, reverse, and ratio shifting sensitivity) all to 0 on the dash screen

4. 4

   Ensure the PTO, differential lock, and front axle are completely disengaged to prevent interference with the calibration process

1. 1

   Prepare tractor for calibration

   Position the tractor on flat ground, place the transmission in neutral, and release the parking brake.

2. 2

   Adjust engine speed

   Raise the engine speed to 1500 RPM (± 100 RPM) using the hand throttle.

3. 3

   Initiate calibration sequence

   Raise the PowerShuttle arm to the "raised" position (left of the steering wheel) and hold it there while simultaneously pressing the differential lock switch.

4. 4

   Hold controls until prompt

   Hold both for approximately 3 to 10 seconds until the right-hand instrument panel (transmission gear screen) displays "Ct".

5. 5

   Begin calibration

   Once "Ct" is displayed, place the PowerShuttle arm into the forward position to begin the calibration.

6. 6

   Allow calibration to complete

   Allow the tractor to calibrate. This takes approximately 10 minutes. It is completely normal to hear the transmission shifting and making noises during this time.

7. 7

   Verify calibration completion

   Once calibration is complete, the screen will stop displaying "Ct" and will show the last transmission ratio you were in (e.g., "1A/2A" or "1E/2E").

8. 8

   Save settings

   To save the new settings, place the PowerShuttle into the neutral position, disengage the differential lock, idle the tractor down, and switch the engine off.

9. 9

   Validate settings

   Restart the tractor and validate the settings by driving back and forth using a variety of maneuvers to ensure shifting is smooth.
