Special Instructions

K-4491 should be installed on transmissions built prior to July 29th, 2019 serial number Z0123456 whenever a transmission is removed. Contact the Roadranger Call Center at 1-800-826-4357 for warranty guidelines. K-4491 will be added to new production transmissions targeted to be built 07/19/2021.

Special Tools

  • ServiceRanger
  • Transmission Assembly Lube (Lubegard® Assemblee Goo Firm Tack - Green #19250 or equivalent)
    Notice
    Only use the specified transmission assembly lube indicated above. Other types of assembly lube or grease reduce O-ring effectiveness.
  • Non-Chlorinated Brake Cleaner
    Danger
    Do not handle non-chlorinated brake cleaner until all manufacturer precautions have been read and understood. Failure to follow precautions will result in serious personal injury or death.
    Caution
    Avoid contact between non-chlorinated brake cleaner and the transmission plastic components, electrical wiring and connectors. Failure to avoid contact will result in transmission component damage.

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. 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.
