Problem: Transmission Slipping in 2022 Toyota Highlander

Symptoms:

  • Delay in acceleration
  • Engine revving without corresponding increase in speed
  • Harsh or erratic shifting
  • Transmission warning light may illuminate on the dashboard
  • Unusual noises (grinding or whining) when changing gears
Repair Instructions

  1. Fluid Change:

    • If the transmission fluid is low or burnt:
    • Tools Required:
      • Transmission fluid (Toyota Genuine ATF WS)
      • Fluid pump
      • Transmission filter (if applicable)
    • Instructions:
      1. Remove the transmission pan (if equipped) with a socket wrench.
      2. Drain the old fluid into a container.
      3. Replace the transmission filter if applicable.
      4. Clean the transmission pan and magnet thoroughly.
      5. Reinstall the pan and torque bolts to specification.
      6. Use a fluid pump to refill the transmission with new fluid through the dipstick tube (if applicable).
      7. Start the engine, let it idle, and check the fluid level, adding more if necessary.

  2. Transmission Reset:

    • If DTCs indicate a transmission control issue:
    • Instructions:
      1. After addressing any fluid issues, reset the transmission control module (TCM) by disconnecting the battery for about 10 minutes.
      2. Reconnect the battery and drive the vehicle to allow the TCM to relearn the shift patterns.

  3. Mechanical Repairs:

    • If internal transmission issues are suspected (e.g., worn clutches, bands, or solenoids), the transmission will likely need to be disassembled and repaired or rebuilt by a professional.
    • Instructions:
      1. Remove the transmission from the vehicle.
      2. Disassemble the transmission to access internal components.
      3. Inspect clutches, bands, and solenoids for wear.
      4. Replace any worn components and reassemble the transmission.
      5. Reinstall the transmission and refill with the correct fluid.
Final Steps

  1. Test Drive:

    • After repairs, conduct a thorough test drive to ensure the transmission operates smoothly without slipping.

  2. Check for DTCs Again:

    • After the test drive, check for any new DTCs to confirm the repair's success.

  3. Customer Follow-Up:

    • Advise the vehicle owner on maintenance schedules for the transmission fluid and potential signs of future issues.
Conclusion

If the slipping issue persists after performing the above steps, it's advisable to consult with a certified transmission specialist or authorized Toyota service center for further diagnosis and potential repair options.
