Solution

1. Preparation

Tools Required:
- Wrench set
- Socket set
- Transmission funnel
- Drain pan
- Torque wrench
- OBD-II scanner (if necessary)
Raise the vehicle using ramps or a jack and secure it with jack stands.
Ensure the vehicle is on a level surface and the engine is off.

2. Drain Old Transmission Fluid

Place a drain pan underneath the transmission pan.
Remove the transmission pan bolts using the appropriate socket.
Carefully lower the pan to drain the old fluid. Be cautious of any remaining fluid that may spill.
Clean the pan and inspect for metal shavings or debris.

3. Replace Transmission Filter (if applicable)

Once the pan is removed, locate the transmission filter.
Remove the old filter by unfastening any retaining clips or screws.
Install the new transmission filter, ensuring it is seated properly.

4. Reinstall Transmission Pan

Apply a new gasket or RTV sealant to the transmission pan's mating surface.
Position the transmission pan back onto the transmission and hand-tighten the bolts.
Use a torque wrench to tighten the pan bolts to the specified torque (usually around 10-12 ft-lbs, refer to the manual).

5. Fill New Transmission Fluid

Locate the transmission fluid dipstick tube or filler plug.
Insert a funnel and pour in the recommended type and amount of new transmission fluid.
Start the engine and let it idle for a few minutes, cycling through all gears (with foot on the brake).
Check the fluid level using the dipstick and add more fluid if necessary.
