Case IH 82 – TRANS (Transmission Controller): Creep Clutch is not calibrated

The transmission control module has detected that the calibration values for the creeper clutch are missing, out of range, or have been cleared from the system's memory. This often happens after a software reset, battery replacement, or if service work has been performed on the transmission valves, master clutch, or transmission controller.

1. 1

   Check for related fault codes, specifically code 113 (Creeper clutch solenoid or wiring failed open/shorted), which will cause calibration to fail

2. 2

   Verify transmission fluid temperature is warmed to more than 60°C (140°F)

3. 3

   Ensure the engine can maintain a steady speed of 1200 RPM or higher

4. 4

   Visually inspect the creeper clutch solenoid and wiring harness on the transmission control valve body for physical damage from debris

1. 1

   Warm transmission oil

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

2. 2

   Prepare tractor for calibration

   Turn off the air conditioning and apply the park brake.

3. 3

   Enter calibration mode

   Enter the transmission calibration mode. On many models, this is done by holding the Upshift rocker switch while starting the engine, which will display 'CAL' on the instrument cluster. Alternatively, navigate to the 'H1' (Transmission clutch spring pressure calibration) menu in the diagnostic display.

4. 4

   Set engine speed

   Set the engine speed to 1200 RPM (± 100 RPM).

5. 5

   Set levers

   Place the range lever in neutral and the shuttle lever in forward.

6. 6

   Begin calibration

   Press and hold the Upshift button to begin calibrating the clutches sequentially. The display will show a flashing number that scrolls up as the clutch fills.

7. 7

   Monitor calibration progress

   When the processor detects a 50 RPM drop in engine speed, the calibration for that specific clutch stops, and the number will turn solid.

8. 8

   Cycle through clutch packs

   Follow the on-screen prompts (using the upshift/downshift switches) to cycle through all clutch packs (C1, C2, C3, C4, and the Creep Clutch).

9. 9

   Save calibration

   Once the display shows 'END' or the calibration values are saved, turn the engine off to store the calibration in the non-volatile memory.

10. 10

    Replace solenoid if calibration fails

    If the calibration fails on the creep clutch step, the creeper solenoid valve is likely sticking or failing electrically and must be replaced.
