Solution

1. Preparation

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

2. Fluid Change

Sub-steps:
1. Remove the transmission drain plug (if equipped) or the transmission pan.
2. Allow old fluid to drain completely into a suitable container.
3. Replace the transmission filter if applicable.
4. Clean the transmission pan and magnet, and inspect for metal debris.
5. Reinstall the drain plug or transmission pan with a new gasket, torquing bolts to manufacturer specifications (typically around 8-12 ft-lbs).
6. Refill the transmission with the manufacturer-recommended fluid (e.g., Toyota ATF WS) to the correct level.

3. Component Inspection and Replacement

Sub-steps:
1. Remove any necessary components to access the transmission solenoids.
2. Disconnect electrical connectors and remove faulty solenoids.
3. Install new solenoids, ensuring they are seated properly and connectors are secured.
4. Reassemble any removed components, ensuring all connections are tight.

4. Reprogramming (if applicable)

Sub-steps:
1. Use a compatible scan tool to check for the need for software updates or reprogramming of the transmission control module.
2. Follow the manufacturer's instructions to perform any necessary updates.
