2. Clean the pan and replace the filter, if applicable.
3. Reinstall the pan with a new gasket and torque to manufacturer's specifications (check the service manual for torque values).
4. Refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.

3. Check and Replace Transmission Solenoid (if necessary)

Sub-steps:
1. Locate the transmission solenoid assembly as per the service manual.
2. Disconnect the electrical connector and remove the retaining bolts.
3. Replace the solenoid with a new unit, ensuring proper orientation.
4. Reconnect the electrical connector securely.

4. Inspect and Repair Shift Linkage

Sub-steps:
1. Visually inspect the shift linkage for any signs of wear or damage.
2. Adjust or replace any misaligned or damaged components.
3. Ensure all connections are tight and functioning smoothly.

5. Reconnect Battery and Test Drive

Reconnect the battery and perform a test drive to ensure the issue has been resolved.
