Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Reinsert the dipstick and remove it again to check the fluid level.
3. If low, add the recommended type of transmission fluid (Toyota ATF WS).
4. If fluid is dark or has a burnt smell, drain the transmission fluid.
  - Use a socket set to remove the transmission pan bolts.
  - Carefully lower the transmission pan and drain the old fluid.
  - Inspect the pan for debris and clean it thoroughly.
5. Replace the transmission filter if present (if applicable to your model).
6. Reinstall the transmission pan with a new gasket and torque bolts to manufacturer specifications (typically around 8-10 ft-lbs).

3. Inspect and Replace Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids on the transmission body.
2. Disconnect the electrical connectors and remove the solenoids.
3. Test solenoids with a multimeter for resistance (should be within OEM specifications).
4. Replace any faulty solenoids with new ones.
5. Reconnect the electrical connectors.

4. Adjust Transmission Linkage

Sub-steps:
1. Inspect the transmission linkage for any misalignment or damage.
