1. Identify any leaking seals around the transmission housing.
2. Remove the necessary components to access the seals.
3. Carefully remove old seals and clean the mating surfaces.
4. Install new seals, ensuring they are seated properly.
5. Reassemble any removed components.

4. Check and Replace Transmission Control Module (if necessary)

Sub-steps:
1. Disconnect the battery again for safety.
2. Locate the transmission control module (usually near the transmission).
3. Disconnect the wiring harness from the TCM.
4. Remove the TCM using appropriate tools.
5. Install the new TCM and reconnect the wiring harness.
6. Reconnect the battery and clear any error codes.
