why does my Toyota RAV4 have transmission fluid leaking?

Solution

1. Preparation

• Gather tools and safety equipment.
• Park the vehicle on a level surface and engage the parking brake.
• Allow the engine to cool completely.

2. Raise the Vehicle

• Tools Required: Jack and jack stands.
• Lift the vehicle using a jack and secure it with jack stands for safe access to the underside.

3. Inspect and Repair Leaks

• Transmission Cooler Lines:
  • Remove any clips or fasteners securing the lines.
  • Replace any damaged lines if cracks are found.
• Transmission Pan:
  • Drain the transmission fluid into a pan.
  • Remove the transmission pan bolts using a socket set.
  • Clean the pan and inspect for cracks; replace if necessary.
  • Replace the gasket with a new one and reinstall the pan, torquing the bolts to the manufacturer's specifications (typically 10-12 ft-lbs).
• Seals and Gaskets:
  • Remove any old gaskets or seals carefully.
  • Install new transmission seals where leaks are identified.

4. Refill Transmission Fluid

• Pour the recommended transmission fluid into the dipstick tube using a funnel (consult the owner's manual for the correct type and amount).
• Start the engine and check for leaks around the repaired areas.

5. Lower the Vehicle

• Carefully remove the jack stands and lower the vehicle back to the ground.
