    _Graphics/_Raster/IMG_3325.png

Install Harness Bracket

Note: This procedure contains installing the Harness Bracket without the Mechatronic Transmission Module (MTM).

  1. Install Harness Bracket

    _Graphics/_Raster/TRSM0950_MSEP_7802.png

  2. Install 3 Harness Bracket 10 mm cap screws and torque to 8.8-10.4 Nm (6-8 lb-ft).

    _Graphics/_Raster/TRSM0950_MSEP_7788.png

Install Mechatronic Transmission Module (MTM)

  1. Place the transmission in a horizontal position.

    Notice
    The transmission must be in a horizontal position prior to the MTM Installation procedure. Failure to do so causes the sliding clutches to move out of neutral and not align to the shift yokes. If the shift yokes are not aligned to the sliding clutches, position sensor fault codes set Active and the transmission will not shift out of neutral.

  2. Clean the sealing surfaces on the transmission and Mechatronic Transmission Module (MTM) with Gasket Remover.

    Notice
    Do not use abrasive scrapers or powered tools to clean sealing surfaces or sealing surfaces may be damaged and leak.

  3. Inspect threaded bolt holes for debris and clean if necessary.

    Notice
    Ensure there is nothing in the threaded bolt holes or the transmission may be damaged when cap screws are tightened.

  4. Install the Rail B Engagement Tool (RR1088TR) to the Main Housing and hand tighten with 2 MTM cap screws.

    _Graphics/_Raster/IMG_0354.png

  5. Shift the Rail B Synchronizer to neutral.

    _Graphics/_Raster/IMG_0362.png

  6. Remove the Rail B Engagement Tool.

  7. Move Rail C and Rail D sliding clutches to neutral.

    Notice
    The transmission must be in a horizontal position prior to the MTM Installation procedure. Failure to do so causes the sliding clutches to move out of neutral and not align to the shift yokes. If the shift yokes are not aligned to the sliding clutches, position sensor fault codes set Active and the transmission will not shift out of neutral.
    _Graphics/_Raster/IMG_0369.png

  8. Install the Confirm-Neutral Gauge (RR1086TR-2) into the slots of the synchronizer and sliding clutches.

    _Graphics/_Raster/IMG_0355.png_Graphics/_Raster/IMG_0365.png

  9. Install the MTM Alignment Tool (RR1086TR-1) onto the main housing.

    _Graphics/_Raster/IMG_0356.png_Graphics/_Raster/IMG_0366.png

  10. Verify synchronizer and sliding clutches are in neutral by sliding Confirm-Neutral Gauge into the slots of MTM Alignment Tool.

    Note: If the gauge does not slide into the alignment tool slots, neutral is not achieved. Go to Step 4.

    _Graphics/_Raster/IMG_0358.png_Graphics/_Raster/TRSM0950_MTM_Ins6.png

  11. Using the Rail E Lever, move Rail E to neutral.

    _Graphics/_Raster/IMG_0370.png_Graphics/_Raster/TRSM0950_MTM_Ins11.png_Graphics/_Raster/TRSM0950_MTM_Ins12.png

  12. Verify Rail E is in neutral using the Gear Side Actuator end of the Confirm-Neutral Gauge (RR1088TR-2) at Shift Rail E. Rail E is in neutral when end of gauge rests against housing with rail against notch-end of gauge.

    _Graphics/_Raster/IMG_0373.png

  13. Move Shift Rail B in the MTM to neutral. Rail B is in neutral when the ball detent is in the notch of the Rail B yoke assembly.

    _Graphics/_Raster/TRSM0950_MTMRailB_N.png

  14. Move Shift Rails C and D in the MTM to neutral. Rails C and D are in neutral when the shift inter-lock is aligned with the notches of the rail yoke assemblies.

    _Graphics/_Raster/TRSM0950_MTMRailsCD_N.png

  15. Verify MTM is in neutral. Install the MTM Alignment Tool (RR1086TR-1) into the bolt hole and onto Rail B, C, and D Shift Yokes.

    Note: If the MTM Alignment Tool slots do not align with the 3 shift yokes, neutral has not been achieved. Go to Step 13.

    _Graphics/_Raster/IMG_0378.png

  16. Verify notch on Rail E is facing up.

    Note: If the MTM is installed on the transmission with the notch on Rail E facing down, Fault Code 320 (SPN 5942) sets Active and the transmission will not shift out of neutral.

    _Graphics/_LineArt/TRSM0950_RailENotch.png

  17. Verify Rail E is in neutral using the Fork Side Actuator end of the Confirm-Neutral Gauge (RR1088TR-2) at Shift Rail E. Rail E is in neutral when end of gauge rests against cover with rail against notch-end of gauge.

    Note: If Rail E is not in neutral, slide rail in or out until neutral is achieved.

  21. Install MTM onto the transmission housing. Align Rail E in the MTM with the Rail E Shift Rail in the Main Housing.

    Caution
    MTM weighs approximately 40 lbs. Keep fingers clear of pinch point between MTM and other surfaces. Dropping MTM could result in component damage and/or personal injury.
    Notice
    If the MTM is installed on the transmission and Rail E in the MTM is not aligned with Rail E in the Main Housing, Fault Code 320 (SPN 5942) sets Active and the transmission will not shift out of neutral.

  22. Install 20 MTM cap screws and torque to 44.5-51.5 Nm (33-38 lb-ft) in a criss-cross pattern.

    Note: 13 mm (x18), 15 mm (x2) cap screws.

Reset and Install Linear Clutch Actuator (LCA)

  1. Inspect LCA to determine next steps, reference images below:

    • If LCA is locked in the reset position, go to Install Linear Clutch Actuator (LCA).
    • If LCA is not locked in the reset position, go to Step 2.

  2. Place LCA push rod on a clean, flat surface. Tightly grasp LCA housing with both hands and push down on push rod to lock LCA into the reset position.

    Caution
    A large amount of force is required to lock the LCA into the reset position. Failure to tightly grasp the LCA housing with both hands while pushing down on push rod may cause unintended movement resulting in personal injury and/or component damage.

  3. Inspect LCA to determine next steps, reference images below:

    • If LCA remains locked in the reset position, go to Step 4.
    • If LCA does not remain locked in the reset position, go to Step 2, repeat reset procedure.

      Note: If LCA cannot be locked into the reset position, replace LCA.

    Caution
    Do not drop LCA. Dropping LCA may cause the LCA to unlock resulting in personal injury and/or 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.
