    _Graphics/_Raster/TRSM0950_OilFill_I1.png

Clutch and Rail Calibration

To ensure proper operation, the TCM, clutch, MTM and transmission require a Clutch and Rail Calibration. Calibrations are automatically initiated when:

  • LCA is in the reset position
  • Transmission in “N” (Neutral)
  • Key on engine running
  • Vehicle air system pressure at operating range
Notice
Do not use service tool to initiate calibrations. Allow calibrations to automatically initiate.

Note: Vehicle display may indicate a flashing “CC” and “F” in gear display.

  1. Set vehicle parking brake and chock wheels.

  2. Key on with engine running.

  3. Allow vehicle air pressure to build to governor cut-off.

    Note: Clutch and Rail Calibrations automatically initiate when vehicle air pressure reaches approximately 100 psi.

  4. Ensure “N” (Neutral) is selected and engine is running. Wait approximately 2 minutes for calibrations to complete.

    Notice
    If process is interrupted, key off, wait 1 minute and go to Step 2.
    • If vehicle display indicates a solid “N: (Neutral) in gear display, calibrations are complete. Key off, go to Step 6.
    • If vehicle display continues to indicate a flashing “CC” and/or “F” in gear display or service transmission message, go to Step 5.
  5. Key off and wait 1 minute.

  6. Key on with engine off.

  7. Connect ServiceRanger.

  8. Go to “Fault Codes”.

    • If an Active transmission fault code is set, go to Endurant HD Troubleshooting Guide TRTS0950 Diagnostic Procedure.
    • If no Active transmission fault codes are set, select “Clear Eaton Faults” and follow on-screen prompts. Go to Step 9.
  9. Disconnect ServiceRanger.

  10. Key off.

  11. Determine next step.

    • If transmission oil was not drained, process complete.
    • If transmission oil was drained, go to Step 12.
  12. Inspect transmission for a PTO.

    • If not PTO-equipped, process complete.
    • If PTO-equipped, start the engine and run for 1 to 2 minutes to fill the PTO with oil, key off and repeat the Fill Oil Procedure.
    Caution
    Failure to repeat the Fill Oil service procedure to verify proper transmission oil level when equipped with a PTO may result in low transmission oil and component damage.
