Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery before starting work on electrical components.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick and remove it.
2. Wipe the dipstick clean and reinsert it to check the fluid level.
3. If low, add the correct type of transmission fluid (Toyota ATF WS) through the dipstick tube.
4. If fluid is burnt or contaminated, proceed to drain and replace.
Tools Required:
- Funnel
- Drain pan
- Socket set
Safety Warnings: Allow the engine to cool before working on the transmission.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan using a socket set, collecting any fluid in a drain pan.
2. Remove the old transmission filter and replace it with a new one.
3. Clean the transmission pan and install a new gasket.
4. Reattach the pan and torque bolts to manufacturer specifications (typically around 10-12 ft-lbs).
Tools Required:
- Socket set
- Torque wrench
- Gasket scraper

4. Test and Replace Solenoids (if necessary)

Sub-steps:
1. Disconnect the electrical connectors from the transmission solenoids.
2. Use a multimeter to test each solenoid for resistance; compare values to factory specifications.
3. If solenoids are faulty, remove and replace them as necessary.
Tools Required:
- Multimeter
- Socket set
