Disconnect the battery to avoid any electrical issues.

2. Change Transmission Fluid and Filter

Sub-steps:
1. Raise the vehicle using jack stands for safe access.
2. Place a drain pan under the transmission pan.
3. Remove the transmission pan bolts and carefully lower the pan to drain old fluid.
4. Remove the old transmission filter and replace it with a new one.
5. Clean the transmission pan thoroughly and replace the pan gasket.
6. Reinstall the transmission pan and torque bolts to manufacturer specifications (consult service manual for torque values).
7. Refill the transmission with the appropriate type and amount of new fluid (consult owner's manual for specifications).

3. Inspect and Replace Solenoids (if needed)

Sub-steps:
1. Locate the transmission solenoids based on your vehicle's service manual.
2. Disconnect the electrical connectors and remove the solenoids.
3. Install new solenoids and reconnect the wiring harness.
4. Ensure all connections are secure.

4. Test Drive

Sub-steps:
1. Reconnect the battery.
2. Start the engine and check for leaks around the transmission pan and solenoids.
3. Take the vehicle for a test drive to ensure the transmission shifts smoothly and slipping is resolved.
