Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, torque wrench, transmission fluid pump, funnel, drain pan.
Ensure the vehicle is parked on a level surface.
Raise the vehicle using a jack and secure it with jack stands.
Allow the engine to run for a few minutes to warm up the transmission fluid.

2. Drain Old Fluid

Locate the transmission pan underneath the vehicle.
Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set (note: some fluid may spill out).
Carefully lower the pan and let the old fluid drain completely.

3. Replace Filter (if applicable)

If your model has a transmission filter, remove the old filter and discard it.
Clean the filter mounting area in the transmission.
Install the new filter, ensuring it is seated properly.

4. Reinstall Transmission Pan

Clean the transmission pan and remove any old gasket material.
Install a new gasket if required.
Reattach the transmission pan and torque the bolts to the manufacturer specifications (typically 7-9 Nm).

5. Fill New Fluid

Locate the transmission fluid fill hole (usually on top of the transmission).
Using a funnel and transmission fluid pump, fill the transmission with the manufacturer-recommended fluid until it reaches the proper level (check the owner's manual for specifications).

6. Check Fluid Level

Start the engine and let it idle.
Shift through all the gears while the vehicle is stationary.
Check the fluid level again and add more fluid as necessary until the proper level is reached.
