Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical shorts.

2. Fluid Change

Drain Transmission Fluid
- Locate the transmission drain plug and place a drain pan underneath.
- Remove the drain plug and allow the fluid to completely drain.
- Reinstall the drain plug and torque it to manufacturer's specifications.
Replace Transmission Filter
- Remove the transmission pan by unscrewing the bolts.
- Carefully lower the pan and remove the old filter.
- Install the new filter, ensuring it is seated properly.
Reinstall Transmission Pan
- Clean the mating surface of the transmission and the pan.
- Apply a new gasket or sealant as per the manufacturer's recommendation.
- Reattach the pan and torque the bolts to the specified value.

3. Replace Transmission Solenoids (if defective)

Access Transmission Solenoids
- Remove any components obstructing access to the solenoids, such as the air intake or battery tray.
Unplug and Replace Solenoids
- Disconnect the electrical connectors from the solenoids.
- Remove the old solenoids and install the new ones.
- Reconnect the electrical connectors securely.

4. Check for Leaks

Start the engine and allow it to reach operating temperature.
Inspect the transmission area for any signs of leaks around the pan and solenoids.
