my Toyota RAV4 XA40 (2013-2018) is leaking transmission fluid what should I do

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is on a level surface and securely lifted with jack stands.
• Disconnect the battery to prevent electrical issues.

2. Identify and Clean the Leak Source

• Wipe down the transmission area to remove old fluid and debris, making it easier to identify the exact leak point.
• Examine the transmission pan and other components to pinpoint the source of the leak.

3. Replace Damaged Components

• For a leaking transmission pan:

  • Drain the transmission fluid from the pan.
  • Remove the transmission pan bolts with a socket set.
  • Carefully detach the pan and replace the gasket with a new one.
  • Reinstall the pan and torque the bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs).

• For leaking seals or gaskets:

  • Remove the old seal or gasket using a scraper or seal removal tool.
  • Clean the mating surfaces thoroughly.
  • Install the new seal or gasket ensuring it is seated properly.

4. Refill Transmission Fluid

• Refill the transmission with the appropriate type of fluid (Toyota ATF WS) using a funnel.
• Start the engine and let it idle, then shift through each gear to circulate the fluid.
• Check the fluid level on the dipstick and add more fluid if necessary.

5. Final Checks

• Inspect the repair area for any signs of new leaks.
• Reconnect the battery and check for warning lights on the dashboard.
