Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and securely lifted.
Disconnect the negative battery terminal.

2. Check and Replace Transmission Fluid

Step 1: Remove the transmission dipstick and wipe it clean.
Step 2: Insert the dipstick back into the tube and remove it again to check the fluid level.
Step 3: If low, add the correct type of transmission fluid (Toyota ATF WS).
Step 4: If the fluid is dirty or burnt, proceed to drain and replace it.
Step 5: Place a drain pan under the transmission pan and remove the pan bolts using a socket set.
Step 6: Carefully lower the pan, allowing the fluid to drain completely.
Step 7: Replace the transmission filter if applicable and clean the mating surfaces.
Step 8: Reinstall the pan with a new gasket and torque the bolts to the manufacturer's specification (typically 8-10 ft-lbs).

3. Inspect and Repair Transmission Components

Step 1: Reconnect the transmission linkage and ensure it is properly adjusted.
Step 2: Remove and test the transmission solenoids using a multimeter for proper resistance values (refer to service manual for specifications).
Step 3: Replace any faulty solenoids as needed.
Step 4: Check the condition of the transmission seals and gaskets; replace if damaged.

4. Refill Transmission Fluid

Step 1: With the vehicle running and in park, use a funnel to add new transmission fluid through the dipstick tube.
Step 2: Check the fluid level again after adding fluid and adjust as necessary.
