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 issues.

2. Inspect and Change Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and check the fluid level and condition. If the fluid is burnt or low, it needs replacement.
2. Place a drain pan under the transmission and remove the transmission pan bolts using a socket set.
3. Carefully lower the transmission pan to drain old fluid. Clean the pan and magnet inside for debris.
4. Replace the old transmission filter if applicable. Remove old filter and install the new one securely.
5. Reinstall the transmission pan with a new gasket, ensuring it is torqued to manufacturer specifications (usually around 10-12 ft-lbs).
6. Fill the transmission with new fluid using the correct type (typically Toyota Type T-IV or WS) through the dipstick tube until the proper level is reached.

3. Check for Component Damage

Sub-steps:
1. Inspect the transmission cooler lines for blockages or leaks, replacing any damaged components.
2. Check the condition of the torque converter; if it is faulty, it may need to be replaced.
3. If internal components are found to be damaged during inspection, a complete transmission rebuild or replacement may be necessary.

4. Reconnect Battery and Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature.
Cycle through all gears while checking for leaks and ensuring proper shifting.
