Solution

1. Preparation

Gather tools and materials required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Check Fluid Level

Remove the transmission dipstick.
Wipe it clean, reinsert it, and remove it again to check the fluid level.
If the fluid is low, top it up with the appropriate transmission fluid type as specified in the owner's manual.

3. Inspect Seals and Gaskets

Use a socket set to remove any components obstructing access to the transmission seals (e.g., exhaust pipes, heat shields).
Visually inspect the transmission mounts, seals, and gaskets for cracks or signs of wear.
If any parts are damaged, proceed to replace them.

4. Address Transmission Pan

If the transmission pan is found to be leaking, drain the transmission fluid into a suitable container.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the pan and replace the gasket with a new one.
Reinstall the pan and torque the bolts to the specified value (check service manual for torque specifications).
Refill the transmission with the appropriate fluid.

5. Perform Leak Test

After repairs, start the vehicle and allow it to reach operating temperature.
Check for leaks around repaired areas while the engine is running.
