Solution

1. Preparation

Tools Required:
- Socket set
- Pliers
- OBD-II scanner
- Transmission fluid pump
- Torque wrench
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery before starting any electrical work.

2. Check and Replace Transmission Fluid

Locate the transmission dipstick and remove it to check fluid level.
If low, add the manufacturer-recommended transmission fluid (Toyota ATF WS).
If the fluid is dark or smells burnt, proceed to replace the fluid.
Raise the vehicle using jack stands for safety, then remove the drain plug and allow fluid to drain completely.
Replace the transmission filter by removing the transmission pan (make sure to clean the pan and magnet).
Install a new filter, ensuring it is properly seated, then reattach the transmission pan with a new gasket, tightening the bolts to the specified torque (approximately 7-9 ft-lbs).

3. Inspect and Replace Transmission Solenoids (if necessary)

Remove the transmission pan again if the solenoids are located inside.
Disconnect the electrical connectors from the solenoids.
Use a multimeter to test solenoid resistance as per the specifications in the service manual.
If faulty, replace the solenoids using the appropriate torque specifications for installation.
Reassemble the transmission pan.

4. Road Test

Reconnect the battery.
Start the engine and allow it to warm up.
Check for leaks around the transmission pan and solenoid areas.
Conduct a road test to ensure the slipping issue is resolved.
