3. Fluid Level Check

Sub-steps:
- Locate the transmission fluid access point as per the service manual.
- Remove the access cover (if applicable) and insert a dipstick or fluid level gauge to check the fluid level.
- If the fluid is low, add the recommended transmission fluid until it reaches the correct level as specified in the owner’s manual.

4. Seal and Gasket Replacement (if leaks found)

Sub-steps:
- Drain the transmission fluid if necessary to work on seals.
- Remove the affected seals or gaskets carefully using a scraper tool.
- Clean the mating surfaces thoroughly to ensure a good seal.
- Install new seals or gaskets, applying any required sealant as specified by the manufacturer.
- Refill transmission fluid to the appropriate level.

5. Final Checks

Sub-steps:
- Reconnect the battery.
- Start the vehicle and allow it to reach operating temperature.
