Solution

1. Preparation

Gather tools and parts required for the fluid change.
Ensure the vehicle is on a level surface and the engine is warmed up for accurate fluid measurement.

2. Drain Old Transmission Fluid

Tools Required: Socket set, drain pan, funnel, new transmission fluid.
Locate the transmission drain plug underneath the vehicle.
Place the drain pan under the transmission and remove the drain plug using the socket set.
Allow the old fluid to completely drain into the pan.

3. Replace Transmission Filter (if applicable)

Tools Required: Socket set, filter wrench, new transmission filter (if applicable).
Remove the transmission pan bolts using the socket set.
Carefully lower the pan to avoid spilling fluid.
Remove the old filter and replace it with a new one, ensuring the rubber O-ring is properly seated.

4. Refill Transmission Fluid

Tools Required: Funnel, new transmission fluid (specific to Genesis G70 specifications).
Replace the transmission pan and secure it with the bolts, tightening to manufacturer specifications (typically around 10-15 ft-lbs).
Remove the dipstick and use a funnel to pour new transmission fluid into the fill tube.
Refer to the owner’s manual for the correct type and amount of fluid (typically around 8-12 quarts for a full change).

5. Check Fluid Level and Test

Start the engine and allow it to idle.
Cycle through all gears with the brake pedal pressed to circulate the fluid.
Check the fluid level with the dipstick and add more fluid if necessary.
Ensure the fluid is at the correct level, and check for leaks around the pan and drain plug.
