Case IH 2364 – Transmission Control Unit (TCU): Even Clutch not calibrated

The transmission controller does not have the required calibration values saved in its memory for the 'Even' clutch pack. This condition typically occurs when a new transmission controller is installed, after a software update, or if a previous transmission calibration sequence was interrupted or failed.

1. 1

   Check for active electrical faults for the transmission solenoids (e.g., code 2353). If an electrical fault exists, the calibration will fail.

2. 2

   Check transmission fluid temperature. The oil must be warmed up to operating temperature (60°C to 105°C / 140°F to 220°F) before calibration.

3. 3

   Perform a safety check: ensure the tractor is parked on a flat, open surface away from obstacles and people, as the machine may lunge automatically during the calibration process.

1. 1

   Warm transmission fluid

   Start the tractor and warm the transmission fluid to at least 60°C (140°F).

2. 2

   Park and engage brake

   Park in a clear area and engage the parking brake.

3. 3

   Access CONFIG MENU

   Turn the key switch to the ON position. Within 10 seconds, press and hold the Enter key on the keypad to access the CONFIG MENU.

4. 4

   Select TCU

   Use the down arrow key to highlight TCU (Transmission Control Unit) and press Enter.

5. 5

   Access ETC MENU

   Scroll down to the ETC MENU and press Enter to access the transmission sub-menus.

6. 6

   Access TRANS SETUP

   Scroll until the TRANS SETUP screen displays, then press Enter.

7. 7

   Select Clutch Calibration

   Select Cltch Cal (Clutch Calibration) and press Enter.

8. 8

   Verify temperature

   The screen will display Oil Deg, showing the current hydraulic fluid temperature. If the temperature is within the 60 - 105°C range, press Enter to continue.

9. 9

   Run calibration

   Follow the on-screen prompts to run the automated calibration. The controller will cycle through the clutches (including the Even clutch) to learn their fill times and engagement pressures.

10. 10

    Complete calibration

    Once the sequence completes successfully, the new values are stored, and code 2364 will clear.
