Disconnect the battery to prevent electrical shorts.

2. Transmission Fluid Change

Sub-steps:
1. Raise the vehicle with a jack and secure it on jack stands.
2. Place a drain pan under the transmission pan.
3. Remove the transmission pan bolts using a socket wrench.
4. Carefully lower the transmission pan and drain the old fluid completely.
5. Inspect the transmission filter; replace it if it shows signs of clogging or damage.
6. Clean the transmission pan and replace the pan gasket.
7. Reinstall the transmission pan and torque the bolts to the manufacturer's specifications.
Tools Required:
- Socket set
- Torque wrench
- Drain pan
- New transmission fluid
- New transmission filter

3. Inspect and Replace Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids (usually found on the valve body).
2. Disconnect the electrical connectors and remove the solenoid retaining bolts.
3. Remove the solenoids and inspect them for wear or damage.
4. Install new solenoids and reconnect the electrical connectors.
5. Ensure all connections are secure before moving on.
Tools Required:
- Socket set
- Screwdriver set
