Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical shorts.

2. Fluid Change

Sub-steps:
1. Locate the transmission fluid drain plug and place a drain pan underneath.
2. Remove the drain plug and allow the old fluid to completely drain.
3. Replace the drain plug and torque to the manufacturer's specifications (typically around 25 ft-lbs).
4. Remove the transmission fluid fill plug and add new transmission fluid that meets Toyota specifications (typically Toyota ATF WS) using a funnel.
5. Check the fluid level using the dipstick and add fluid as necessary.

3. Inspect and Repair Linkage/Cables

Sub-steps:
1. Locate the transmission linkage and inspect for any signs of damage or misalignment.
2. Adjust or replace any damaged linkage or cables as needed.
3. Lubricate pivot points to ensure smooth operation.

4. Test Transmission Solenoids

Sub-steps:
1. Disconnect the electrical connector from the transmission solenoid.
2. Use a multimeter to check the resistance of the solenoids according to specifications.
3. Replace any faulty solenoids with new OEM parts.

5. Check Clutch (if applicable)

Sub-steps:
1. For manual transmissions, inspect the clutch master cylinder and slave cylinder for fluid leaks.
2. If necessary, bleed the clutch hydraulic system to remove air.
3. Replace worn clutch components if they do not function properly.
