• Transmission Service: Start with a transmission fluid flush and filter replacement to ensure proper fluid flow and cooling.
• Diagnostic Scan: Perform a diagnostic scan to identify error codes and pinpoint transmission-related issues.
• Repair or Replacement: The course of action taken hinges on the severity of the issue. Problem, repair, or replace damaged transmission components such as solenoids, seals, or the torque converter.

Recommendation: Refer to the transmission troubleshooting section in the manual for guidance on diagnosing and repairing transmission problems.

• • Immediate Inspection: If you suspect rear axle breakage, Stop operating the vehicle immediately and arrange for it to be towed to a certified mechanic promptly for inspection.
  • Replacement: If the rear axle is broken, it will likely need to be replaced with a new or refurbished unit.
  • Check for Recalls: Check for any recalls or service bulletins related to rear axle issues and follow manufacturer recommendations for repairs.
  
  

  The manual suggests Checking the rear axle. Refer to the maintenance section for guidance on inspection and repair procedures.

• • • Check Transmission Fluid: Ensure the transmission fluid level is correct and not burnt. Top up or replace fluid as needed.
    • Diagnostic Scan: Conduct a diagnostic scan to retrieve error codes and identify specific transmission issues.
    • Repair Transmission Components: Address any faulty transmission components, such as solenoids, sensors, or the valve body, that may be causing the problem.
    
    

    Recommended: The manual's transmission troubleshooting section guides you through diagnosing and repairing O/D light blinking and hard shifting issues.

• • • • Visual Inspection: Inspect vacuum hoses, connections, and intake manifold gaskets for signs of wear, cracks, or disconnection.
      • Smoke Test: Perform a smoke test to detect vacuum leaks by introducing smoke into the intake system and observing any leaks.
      • Replace Faulty Components: Replace damaged vacuum hoses, intake manifold gaskets, or other components contributing to vacuum leaks.
      
      

      Recommended solution: Check the vacuum system maintenance. Refer to the manual section for guidance on identifying and repairing vacuum leaks.

• • • • • • Inspect Intake Runner: Check the intake runner for signs of damage or looseness that may be causing the knocking noise.
          • Tighten or Replace Intake Runner: If the intake runner is loose or broken, tighten or replace it as necessary to eliminate the knocking noise.
          • Address Other Engine Issues: If the knocking persists, inspect other engine components, such as the valves, lifters, or timing components, for potential issues.
