Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with jack stands.
Disconnect the battery to avoid electrical shorts.

2. Check Transmission Fluid

Tools Required: Transmission dipstick, funnel.
Remove the transmission dipstick and wipe it clean.
Insert the dipstick back into the tube and remove it again to check the fluid level.
If the fluid is low, add the appropriate Toyota ATF WS fluid until it reaches the correct level.

3. Replace Transmission Filter and Fluid

Tools Required: Socket set, fluid pump, replacement filter, new transmission fluid.
Remove the transmission pan using a socket set, being careful to catch any fluid in a pan.
Remove and replace the transmission filter.
Clean the transmission pan and replace the gasket.
Reinstall the pan and torque bolts to manufacturer specifications (typically around 8-10 ft-lbs).
Refill with new transmission fluid through the dipstick tube using a fluid pump.

4. Inspect and Replace Transmission Solenoids

Tools Required: Socket set, multimeter (for testing), replacement solenoids.
Disconnect the electrical connector for the solenoids.
Remove the solenoid assembly from the transmission.
Test solenoids with a multimeter for resistance and functionality.
Replace any faulty solenoids as needed and reinstall the assembly.

5. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and allow it to warm up.
Test drive the vehicle to ensure that the slipping issue has been resolved.
