why does my Toyota RAV4 XA50 (2019-2024) feel like it's slipping gears

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Transmission Fluid Change

• Sub-steps:
  1. Locate the transmission fluid pan under the vehicle.
  2. Remove the transmission pan bolts using a socket set.
  3. Carefully lower the pan and drain the old fluid into a container.
  4. Inspect the pan for metal shavings or debris, indicating internal wear.
  5. Replace the transmission filter if applicable.
  6. Reinstall the pan with a new gasket and torque bolts to the manufacturer’s specifications.

3. Shift Solenoid Inspection

• Sub-steps:
  1. Locate the shift solenoids (usually found on the valve body).
  2. Disconnect the electrical connectors from the solenoids.
  3. Use a multimeter to check for continuity and resistance as per manufacturer specifications.
  4. Replace any faulty solenoids with new parts.

4. Transmission Control Module (TCM) Reset

• Sub-steps:
  1. Reconnect the negative battery terminal.
  2. Start the vehicle and allow it to reach operating temperature.
  3. Perform a TCM reset by following the specific procedure in the service manual (often involves disconnecting the battery for a period and then reconnecting).
