Solution

1. Preparation

Gather necessary tools and parts before starting.
Ensure the vehicle is parked on a level surface and the engine is cool.
Gather tools:
- Socket set
- Torque wrench
- Transmission fluid pump
- Drain pan
- Funnel
- Rags for cleanup
Safety warning: Disconnect the battery to avoid electrical issues during the process.

2. Drain the Old Fluid

Place a drain pan under the transmission oil pan.
Remove the transmission oil pan bolts using a socket wrench.
Carefully lower the pan to allow the old fluid to drain completely; be cautious as fluid may still be warm.
Inspect the magnet inside the pan for metal shavings, which can indicate internal wear.

3. Replace the Filter (if applicable)

If your model is equipped with a transmission filter, remove the old filter.
Clean the filter mounting surface.
Install the new filter, ensuring it is seated properly.

4. Reinstall the Oil Pan

Clean the oil pan and remove any old gasket material.
Apply a new gasket or gasket maker as per manufacturer specifications.
Reinstall the oil pan and torque the bolts to the manufacturer's specified torque values (typically around 8-10 Nm).

5. Add New Transmission Fluid

Use a transmission fluid pump to fill the transmission with the recommended fluid type through the dipstick tube.
Add fluid slowly while monitoring the level on the dipstick.
Start the vehicle and let it run for a few minutes, then check the fluid level again, adding more if necessary.

6. Final Checks

After filling, cycle through all gears (including reverse) and check for smooth shifting.
Check for leaks around the oil pan and fittings after the vehicle has run for a while.
