Case IH 2363 – Transmission Control Unit (TCU): The Odd Clutch is not calibrated

The transmission controller detects that the calibration values for the odd-numbered gear clutch pack are missing, out of range, or incomplete. This often happens after a new controller is installed, after a battery replacement/power loss, or if a previous calibration attempt was aborted or failed.

1. 1

   Check for Electrical Faults: Verify there are no active fault codes related to the Odd Clutch Solenoid (e.g., TRANS 104, 116, 2342, or 2354) indicating a short or open circuit. Calibration is impossible if an electrical fault exists.

2. 2

   Check Fluid Temperature: Ensure the transmission fluid is warmed up to between 60°C and 105°C (140°F - 221°F) for optimum calibration results.

3. 3

   Ensure Safety & Environment: Verify the tractor is parked in an open area free of obstacles, on a flat surface, with the parking brake engaged.

1. 1

   Warm up transmission fluid

   Start the engine and warm the transmission oil temperature to at least 60°C (140°F).

2. 2

   Prepare machine for calibration

   Park on a flat surface, engage the parking brake, and ensure the area around the machine is clear.

3. 3

   Access CONFIG MENU

   Turn the key switch to the ON position. Within ten seconds, press and hold the Enter key on the keypad to bring up the CONFIG MENU.

4. 4

   Select TCU

6. 6

   Access TRANS SETUP

   Press the down arrow key until the TRANS SETUP screen displays, then press Enter.

7. 7

   Begin Clutch Calibration

   The Cltch Cal (clutch calibration) screen will display. Press Enter to begin.

8. 8

   Verify Oil Temperature

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

9. 9

   Calibrate Odd Clutch

   The system will automatically begin calibrating the clutches. When the Odd Clutch calibration completes, the screen will display the calibration value in milliamperes (mA).

10. 10

    Continue Calibration

    Press the Enter key to continue to the next clutch (e.g., Even Clutch) until all clutches are successfully calibrated.
