Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fluid catch pan, and transmission fluid.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to prevent any electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick and check the fluid level.
2. If low, add the recommended type of transmission fluid (Toyota ATF WS).
3. If fluid is dirty or burnt, drain the old fluid using a fluid catch pan.
4. Replace the transmission pan gasket and install a new transmission filter if necessary.
5. Refill the transmission with fresh fluid through the dipstick tube.

3. Inspect and Replace Transmission Solenoids

Sub-steps:
1. Remove the transmission pan to access the solenoids.
2. Disconnect the solenoid connectors and inspect for corrosion or damage.
3. Use a multimeter to test the resistance of each solenoid; replace any that are out of spec.
4. Reinstall the solenoids and the transmission pan, ensuring proper torque specifications are followed.

4. Adjust or Replace Transmission Bands (if applicable)

Sub-steps:
1. Locate the band adjustment screws (if applicable) on the transmission case.
2. Use a torque wrench to adjust the bands to the manufacturer’s specifications.
3. If bands are severely worn, consider a complete transmission rebuild or replacement.
