Kia Sorento Third Generation (2015-2020) Transmission Fluid Change Interval: What to Know

When it comes to maintaining the transmission of your Kia Sorento, understanding the correct intervals for changing the transmission fluid is crucial for optimal performance and longevity. Below, you will find detailed information about symptoms of low or degraded transmission fluid, recommended change intervals, diagnostic steps, and repair instructions.

Symptoms of Degraded or Low Transmission Fluid
  1. Slipping Transmission: The transmission may struggle to shift or may slip out of gear.
  2. Delayed Engagement: There may be a noticeable delay when shifting from Park to Drive or Reverse.
  3. Unusual Noises: Grinding or clunking noises when the vehicle is in gear may indicate low fluid.
  4. Overheating: The transmission may overheat, causing the temperature warning light to illuminate.
  5. Fluid Leaks: Puddles of red or brown fluid under the vehicle indicate a leak.
Recommended Change Interval
  • General Recommendation: Kia typically recommends changing the transmission fluid every 60,000 miles (96,000 km) under normal driving conditions.
  • Severe Driving Conditions: If the vehicle is frequently driven in severe conditions (towing, extreme temperatures, or stop-and-go traffic), consider changing the fluid every 30,000 to 40,000 miles (48,000 to 64,000 km).
Diagnostic Steps

  1. Check Fluid Level:

    • Tools Required: Transmission dipstick (if applicable), funnel, clean rag.
    • Procedure:
      • With the engine running and the vehicle in Park, pull out the transmission dipstick.
      • Wipe it clean and reinsert it fully.
      • Remove again and check the fluid level. It should be between the "Full" and "Low" indicators.

  2. Inspect Fluid Condition:

    • Tools Required: Clean cloth or paper towel.
    • Procedure:
      • Place a few drops of transmission fluid on a clean cloth.
      • Check the color and smell. Healthy fluid is typically red and should not have a burnt smell.

  3. Look for Leaks:

    • Inspect under the vehicle for any signs of transmission fluid leakage.
Repair Instructions for Changing Transmission Fluid

Tools and Materials Required

  • Transmission fluid (check owner's manual for specifications, typically SP-IV ATF for Kia)
  • Transmission filter (if applicable)
  • Oil catch pan
  • Funnel
  • Ratchet and socket set
  • Torque wrench
  • Pliers
  • Clean rags
  • Safety glasses
  • Gloves

Step-by-Step Procedure

  1. Preparation:

    • Park the vehicle on a level surface and engage the parking brake.
    • Allow the engine to cool down if it has been running.

  2. Drain the Old Transmission Fluid:

    • Place the oil catch pan under the transmission pan.
    • Using a ratchet and socket, remove the transmission pan bolts.
    • Carefully lower the pan, allowing the old fluid to drain completely.

  3. Replace the Transmission Filter (if applicable):

    • Remove the old transmission filter using pliers.
    • Install the new transmission filter, ensuring it's securely seated.

  4. Clean the Transmission Pan:

    • Clean the transmission pan thoroughly using a clean rag.
    • Remove any old gasket material from the pan and transmission mating surfaces.

  5. Reinstall the Transmission Pan:

    • Place a new gasket on the transmission pan.
    • Reinstall the pan and tighten the bolts to the manufacturer’s torque specifications (check the owner's manual for the correct torque values).

  6. Refill Transmission Fluid:

    • Using a funnel, refill with new transmission fluid through the dipstick tube.
    • Start with about 4-5 quarts of fluid; you may need to add more later.

  7. Check Fluid Level:

    • Start the engine and let it reach operational temperature.
    • Shift through all gears, and then back to Park.
    • Check the fluid level again with the dipstick, adding more fluid as necessary.

  8. Test Drive:

    • Take the vehicle for a short test drive to ensure smooth shifting and proper operation.
    • Check for leaks under the vehicle after the test drive.
Conclusion

Changing the transmission fluid in your Kia Sorento is a vital maintenance task that can prevent costly repairs down the road. By adhering to the recommended intervals and following the diagnostic and repair steps outlined above, you can ensure your vehicle's transmission remains in optimal condition for years to come. Always refer to the owner’s manual for specific guidelines related to your vehicle model.
