Allow the vehicle to cool down if it has been running.

2. Transmission Fluid Replacement

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Place a drain pan under the transmission pan.
3. Remove the transmission pan bolts using a socket set and lower the pan carefully to avoid spilling fluid.
4. Replace the transmission filter, ensuring it is seated properly.
5. Clean the transmission pan and magnet (if equipped) of any debris.
6. Reinstall the pan with a new gasket, tightening bolts to the manufacturer's specified torque.
7. Refill the transmission with new fluid through the dipstick tube, using the correct type of fluid as specified in the owner's manual.

3. Inspect and Replace Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids (usually found on the valve body).
2. Disconnect the electrical connectors from the solenoids.
3. Remove the solenoids from the valve body using a socket set.
4. Install new solenoids, ensuring they are properly seated.
5. Reconnect the electrical connectors.
