Solution

1. Preparation

Gather tools and materials: socket set, torque wrench, transmission fluid, gasket scraper, replacement gasket, and a drain pan.
Ensure the vehicle is on a flat surface and lift it securely with jack stands if needed.

2. Drain Transmission Fluid

Position a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the pan to allow fluid to drain completely into the pan.

3. Remove and Inspect Transmission Pan

Remove the transmission pan completely and inspect it for any cracks or damage.
Clean the mating surface on the transmission housing using a gasket scraper to remove old gasket material.

4. Replace Gasket and Reinstall Pan

Place a new transmission pan gasket onto the transmission pan.
Reinstall the transmission pan, ensuring it is properly aligned.
Torque the pan bolts to the manufacturer’s specifications (typically around 10-12 ft-lbs, but verify with the service manual).

5. Refill Transmission Fluid

Use a funnel to refill the transmission with the appropriate type of fluid specified for the Genesis G70 (check the owner's manual).
Start the engine and let it run for a few minutes while shifting through the gears to circulate the fluid.

6. Check for Leaks

After the vehicle has run, inspect the area around the transmission pan for any signs of leaks.
Recheck the transmission fluid level and add more fluid if necessary.
