Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety during repairs.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Locate the transmission dipstick (if applicable) and remove it.
2. Using a funnel, add the manufacturer-recommended transmission fluid if levels are low.
3. Start the engine and let it idle for a few minutes; recheck fluid levels.
Tools Required: Transmission fluid, funnel, dipstick.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan bolts and carefully lower the pan.
2. Remove the old transmission filter and install the new filter.
3. Clean the transmission pan and replace the pan gasket.
4. Reinstall the transmission pan and torque bolts to the manufacturer’s specifications.
Tools Required: Socket set, torque wrench, transmission filter kit.

4. Test and Replace Transmission Solenoids (if necessary)

Sub-steps:
1. Locate the transmission solenoids based on the vehicle’s service manual.
2. Disconnect the electrical connectors and remove the solenoids.
