- Transmission fluid pump
- OBD-II scanner
- Drain pan
- Funnel
Safety Warnings:
- Ensure the vehicle is on a level surface and use jack stands if lifting the vehicle.

2. Drain Old Transmission Fluid

Position a drain pan under the transmission pan.
Remove the transmission pan bolts carefully.
Allow the old fluid to drain completely into the pan.
Inspect the pan and magnets for metal shavings or debris.

3. Replace Transmission Filter (if applicable)

Remove the old filter from the transmission.
Clean the filter mounting area thoroughly.
Install the new transmission filter, ensuring it is seated properly.

4. Install New Transmission Pan Gasket

Clean the transmission pan and ensure the mating surface is free of old gasket material.

Reinstall the transmission pan and torque the bolts to the manufacturer's specifications (usually around 10-12 ft-lbs).

5. Refill Transmission Fluid

Use a transmission fluid pump to fill the transmission with the appropriate type of new fluid (check owner's manual for specifications).
Check the fluid level with the dipstick while the vehicle is running and at operating temperature.
Add fluid as necessary to reach the proper level.
