New Holland TRANS 2364 – Transmission Control Unit (TCU / TRANS): Even Clutch not calibrated

This code indicates that the transmission controller has not successfully learned the fill time and engagement 'kiss point' (measured in milliamperes) for the Even gear clutch pack. This condition often occurs after a new controller is installed, after transmission repairs, or if a previous calibration attempt was aborted or failed.

• New Holland T6 Series (e.g., T6.120)
• New Holland T7 Series (e.g., T7.210, T7030)
• New Holland T8 Series
• New Holland TM Series
• New Holland T5060

1. 1

   Check transmission oil temperature (must be between 60 and 80 degrees Celsius)

2. 2

   Check for active electrical faults or solenoid circuit codes (e.g., TRANS 104 or TRANS 2353) and repair before calibration

3. 3

   Ensure the tractor is parked on a level surface with the handbrake firmly engaged

4. 4

   Ensure the air conditioning is turned off to prevent engine RPM fluctuations during calibration

1. 1

   Warm Up

   Drive the tractor until the transmission oil temperature reaches at least 60°C.

2. 2

   Enter Calibration Mode

   With the engine off, the handbrake applied, and the shuttle lever in Neutral, press and hold both the upshift (bunny) and downshift (turtle) buttons simultaneously, then start the engine.

3. 3

   Verify Temperature

   The display will show the transmission oil temperature. If it is high enough, proceed.

4. 4

   Set RPM

   Use the hand throttle to set the engine speed to exactly 1200 +/- 50 RPM.

5. 5

   Engage Shuttle

   Move the shuttle lever into the Forward position. The display will indicate the first clutch to be calibrated (e.g., 'Even', 'Odd', 'C1', or 'A').

6. 6

   Calibrate the Clutch

   Press and hold the downshift (turtle) button. You will hear the engine RPM drop slightly as the controller engages the clutch and learns the calibration values.

7. 7

   Wait for Completion

   Keep the button depressed until the display shows 'End' or the calibration mA value alternates with the clutch identifier.

8. 8

   Next Clutch

   Release the downshift button. Press the upshift (bunny) button once to cycle to the next clutch pack.

9. 9

   Repeat

   Repeat steps 6 through 8 for all remaining clutches (Odd, Even, C1-C6, Range clutches, Master, etc., depending on the specific transmission).

10. 10

    Save and Exit

    Once all clutches are calibrated and the screen indicates the sequence is finished (often displaying 'CF' or 'syn'), turn the ignition key OFF. This saves the new calibration figures to the processor's non-volatile memory.
