Solution

1. Preparation

Gather tools and parts: Ensure you have an OBD-II scanner, socket set, torque wrench, transmission fluid, transmission filter, and gasket.
Safety precautions: Park the vehicle on a flat surface, engage the parking brake, and allow the engine to cool before starting work.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check fluid level.
2. If fluid is low, add the appropriate type of Toyota ATF (typically Toyota WS fluid).
3. If fluid is burnt or dirty, proceed to replace it.
4. Place a drain pan under the transmission fluid pan and remove the drain plug or pan bolts.
5. Allow fluid to drain completely and replace the drain plug if applicable.

3. Replace Transmission Filter and Gasket

Sub-steps:
1. Remove the transmission pan by unscrewing the bolts with a socket.
2. Carefully lower the pan and remove the old filter from the transmission.
3. Clean the mating surfaces of the transmission and the pan thoroughly.
4. Install the new filter, making sure it is seated properly.
5. Place a new gasket on the transmission pan and reattach it, tightening the bolts to the manufacturer's specified torque (usually around 8-10 ft-lbs).

4. Fill Transmission Fluid

Sub-steps:
1. Use a funnel to add new transmission fluid through the dipstick tube.
2. Start with the amount specified in the owner's manual, typically around 4-6 quarts.
3. Check the fluid level again while the engine is running and adjust as necessary.

5. Test and Monitor

Sub-steps:
1. Start the engine and let it idle for a few minutes.
2. Shift through all gears to ensure proper engagement and listen for any unusual noises.
3. Take the vehicle for a test drive to verify that the slipping has been resolved.
