Solution

1. Preparation

Gather tools and parts needed:
- Tools: Socket set, OBD-II scanner, multimeter, fluid pump, safety goggles, gloves
- Parts: New ATF, new transmission filter, new transmission pan gasket (if necessary)

2. Fluid Change

Drain Old ATF:
1. Lift the vehicle securely using jack stands.
2. Place a drain pan under the transmission pan.
3. Remove the transmission pan bolts using a socket wrench and gently pry the pan off to drain the fluid.
Replace Filter and Gasket:
1. Remove the old transmission filter by unbolting it from the transmission.
2. Install the new filter, ensuring it fits snugly and securely.
3. Clean the transmission pan and remove any old gasket material.
4. Install a new gasket on the transmission pan.
Reinstall Transmission Pan:
1. Position the transmission pan back onto the transmission.
2. Torque the pan bolts to the manufacturer’s specifications (check service manual for specific torque values).

3. Refill ATF

Using a fluid pump, refill the transmission with the recommended type and amount of ATF (consult the owner's manual for specifications).
Start the engine and let it idle for a few minutes.
Shift through all gears with the brake applied to allow the new fluid to circulate.

4. Final Check

Recheck the fluid level with the engine running and adjust as necessary.
Inspect for any leaks around the transmission pan and seals.
