Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, transmission fluid, funnel, rags, and safety gloves.
Ensure the vehicle is parked on a level surface and the engine is turned off. Allow the transmission to cool down to a safe temperature.

2. Fluid Change

Drain Fluid:
- Place a drain pan under the transmission.
- Remove the drain plug (if equipped) or the lower transmission pan bolts to allow old fluid to drain completely.
Replace Filter (if applicable):
- Remove the transmission pan completely to access the filter.
- Replace the old filter with a new one, ensuring the new filter aligns properly.
Reinstall Pan:
- Clean the mating surface of the transmission case and pan.
- Install a new gasket (if applicable) and torque the pan bolts to the manufacturer’s specifications (typically around 8-10 Nm, but refer to the service manual for specifics).

3. Refill Transmission Fluid

Locate the transmission fluid filler cap.
Using a funnel, refill the transmission with the appropriate type and amount of transmission fluid as specified by the manufacturer (typically around 6-8 quarts for a complete change, but refer to the owner's manual).
Start the engine and let it idle for a few minutes; cycle through all gears to properly circulate the new fluid.

4. Verify Fluid Level

After allowing the fluid to circulate, recheck the fluid level using the dipstick while the engine is warm and running.
Add fluid if necessary to bring it to the correct level.
