Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Allow the engine to cool if it was recently running.

2. Drain Old Transmission Fluid

Tools Required: Socket set, drain pan, funnel, 1/2” drive ratchet.
Place the drain pan under the transmission pan.
Remove the transmission pan bolts using the socket set.
Carefully lower the pan to drain the old fluid into the pan. Inspect the magnet for metal shavings that may indicate wear.

3. Replace Transmission Filter (if applicable)

Tools Required: Torque wrench, gasket scraper.
Remove the old transmission filter by unscrewing it or unclipping it depending on the design.
Clean the filter mounting surface to ensure a good seal.
Install the new filter securely.

4. Install New Transmission Fluid and Gasket

Clean the transmission pan and replace the gasket with a new one.
Reinstall the transmission pan using a torque wrench to tighten the bolts to the manufacturer’s specified torque (usually around 10-12 ft-lbs).
Use a funnel to fill the transmission with new fluid through the dipstick tube (consult owner’s manual for the correct type and quantity of fluid).

5. Final Checks

Tools Required: OBD-II scanner (if necessary).
Start the engine and let it idle for a few minutes while checking for leaks.
Shift through all gears with the foot on the brake to circulate the new fluid.
Check the fluid level again and top off as needed.
