Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical shorts.

2. Check and Change Transmission Fluid

Tools Required: Transmission funnel, fluid pump, drain pan, socket set.
Remove the transmission pan bolts using a socket wrench and carefully lower the pan to drain fluid.
Inspect the pan for metal shavings or debris, indicating internal damage.
Replace the old fluid with the manufacturer's recommended transmission fluid (usually ATF WS for Toyota).
Reinstall the transmission pan with a new gasket (if applicable) and torque the bolts to manufacturer specifications.

3. Replace Transmission Filter

Tools Required: Socket set, pick tool, new filter.
Remove any components obstructing access to the transmission filter.
Disconnect the filter from the transmission housing and remove any retaining clips.
Install the new filter in reverse order, ensuring a secure fit.

4. Inspect and Replace Transmission Solenoids

Tools Required: Socket set, multimeter.
Access the transmission solenoids by removing the valve body if necessary.
Test each solenoid with a multimeter to ensure they are within specified resistance range.
Replace any faulty solenoids with new ones, ensuring proper alignment and connection.

5. Reassemble and Refill

Reinstall any removed components in the reverse order of disassembly.
Reconnect the battery.
Refill the transmission with the appropriate fluid to the recommended level.
