Solution

1. Preparation

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

2. Transmission Fluid Change

Drain Old Fluid
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts using a socket set and carefully lower the pan to drain the fluid.
- Inspect the pan for metal shavings or debris.
Replace Filter
- Remove the old transmission filter; note the orientation for the new filter.
- Install the new filter, ensuring it is seated properly.
Reinstall Pan
- Clean the transmission pan mating surface and apply a new gasket or sealant as required.
- Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications (typically around 12-15 ft-lbs).

3. Check and Replace Solenoids (if necessary)

Access Solenoids
- Remove any necessary covers or components to access the solenoids.
Remove Old Solenoids
- Disconnect the electrical connectors and remove the retaining bolts.
- Pull out the solenoids gently.
Install New Solenoids
- Insert the new solenoids in the same orientation as the old ones and secure them with bolts.
- Reconnect the electrical connectors.

4. Refill Transmission Fluid

Add New Fluid
- Using a funnel, fill the transmission with the recommended type and amount of fluid (typically Toyota ATF WS).
- Start the engine and let it idle for a few minutes while cycling through all gears to circulate fluid.
Check Fluid Level
- With the engine still running, check the transmission fluid level on the dipstick and add more fluid if necessary.
