Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to ensure safety.

2. Drain Old Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set and carefully lower the pan.
Allow the old fluid to fully drain into the pan.

3. Inspect and Clean Components

Inspect the transmission filter for clogs or damage; replace if necessary.
Clean the transmission pan thoroughly with solvent to remove sludge and debris.
Check the magnet inside the pan for metal shavings, indicating wear.

4. Replace Transmission Filter (if applicable)

Remove the old filter by pulling it straight off.
Install the new filter, ensuring it is seated properly.

5. Reassemble and Refill Transmission Fluid

Reinstall the transmission pan with a new gasket, tightening the bolts to the manufacturer's specified torque (typically around 10-12 ft-lbs).
Refill the transmission with new fluid through the dipstick tube using the recommended fluid type (often Dexron VI or equivalent).
Start the engine and cycle through all gears to circulate the new fluid.

6. Check Fluid Level

After filling, check the fluid level again with the dipstick. Add fluid as necessary to reach the proper level.
