New Holland 2096 – TCM: Clutch 2 Not Calibrated

The C2 Clutch has not been properly calibrated, meaning the Transmission Control Module (TCM) lacks the necessary data to properly engage or disengage the C2 clutch pack. This condition affects clutch performance and operation, potentially leading to poor shifting performance or a failure to engage certain gears. The fault is typically triggered by the installation of a new controller or if the existing calibration values are lost or corrupted.

1. 1

   Check transmission oil temperature (must be at least 60°C/140°F; check this in the 'HA' menu and avoid 'CL' or 'CH' states).

2. 2

   Ensure engine speed can be set and held at 1200 RPM (+/- 100 RPM).

3. 3

   Verify parking brake is engaged and all remote hydraulic levers are in the neutral position.

4. 4

   Check for other active fault codes, particularly those related to clutch solenoids or pressure sensors, which must be resolved before calibration.

5. 5

   Ensure the operator remains in the seat to keep the operator presence switch engaged during calibration.

1. 1

   Warm up the tractor

   Operate the tractor until the transmission oil reaches the required temperature of at least 60°C.

2. 2

   Enter Calibration Mode

   Connect the diagnostic switch and turn the key on to access the 'HH' menu, then select 'H1'. Alternatively, hold specific buttons (e.g., upshift/downshift or hare/tortoise) while starting the engine until 'CAL' or 'CC' appears on the display.

3. 3

   Set engine speed and levers

   Start the engine, adjust speed to 1200 RPM, and place the shuttle lever in the forward position. For some procedures, other gear levers must also be in specific positions.

4. 4

   Calibrate Clutch 2 (C2)

   When prompted for C2, press and hold the downshift button. The display will show an increasing number as pressure builds to cause a 50 RPM drop. Release the button once a steady value is displayed.

5. 5

   Handle calibration errors

   If calibration fails, note any 'U' codes. U34 indicates calibration is too low (possible mechanical issue or leaking valve). U35 indicates calibration is too high (possible faulty solenoid, sticking clutch, or major leak).

6. 6

   Save and exit

   Once all clutches are calibrated successfully and 'CF' appears on the display, turn the key off to store the new calibration values.
