3. If the fluid is dark or has a burnt smell, proceed to change it.
4. Place a drain pan under the transmission pan.
5. Remove the transmission pan bolts using a socket set, then carefully remove the pan.
6. Clean the pan and replace the filter.
7. Reinstall the pan with a new gasket and torque the bolts to the manufacturer's specifications.
8. Refill the transmission with the correct fluid type through the dipstick tube.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Follow the steps in the previous section to access the transmission filter.
2. Remove the old filter and discard it.
3. Install the new filter, ensuring it is seated correctly.
4. Reassemble the transmission pan.

4. Test Drive and Assess Performance

Sub-steps:
1. Reconnect the battery.
2. Start the engine and allow it to warm up.
3. Shift through all gears to ensure proper function.
