Changing the transmission fluid in your 2007 Toyota Yaris is an essential maintenance task that can help prolong the life of your vehicle's transmission. This guide will walk you through the process, providing you with the necessary information to complete this task effectively.

Transmission Fluid Type

For the 2007 Toyota Yaris with an automatic transmission, use Toyota WS (World Standard) automatic transmission fluid. This specific fluid is designed for optimal performance in Toyota vehicles. Using the correct fluid is crucial to maintain proper transmission function and prevent damage.

Tools and Materials Needed

  • Toyota WS automatic transmission fluid (approximately 3-4 quarts)
  • 10mm hex socket
  • Socket wrench
  • Torque wrench
  • Funnel with a long, narrow spout
  • Drain pan
  • New drain plug gasket
  • Jack and jack stands (if needed)

Draining the Old Fluid

1. Park your Yaris on a level surface and engage the parking brake.

2. Locate the transmission drain plug on the bottom of the transmission pan.

3. Place a drain pan underneath the plug.

4. Use a 10mm hex socket to remove the drain plug carefully.

5. Allow the fluid to drain completely.

Refilling with New Fluid

1. Clean the drain plug and replace the gasket.

2. Reinstall the drain plug and tighten it to 29 ft-lbs (39 Nm) using a torque wrench.

3. Locate the transmission dipstick tube, usually on the passenger side of the engine bay.

4. Use a long, narrow funnel to add new fluid through the dipstick tube.

5. Add approximately 3 quarts of Toyota WS fluid initially.

Checking Fluid Level

1. Start the engine and let it idle for a few minutes.

2. Shift through all gears, then return to Park.

3. With the engine still running, check the fluid level using the dipstick.

4. The fluid should be between the "HOT" marks on the dipstick.

5. Add more fluid if necessary, being careful not to overfill.

Important Notes

  • Never overfill the transmission, as this can cause damage.
  • The exact fluid capacity may vary slightly. Always check the level with the dipstick.
  • If you're unsure about any step, consult a professional mechanic.
