Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical issues.

2. Drain Transmission Fluid

Place the drain pan under the transmission pan.
Remove the bolts securing the transmission pan.
Carefully lower the pan and allow the old fluid to drain completely.

3. Inspect and Replace Gaskets/Seals

Examine the transmission pan gasket and any other seals for damage.
If damaged, remove the old gasket/seal completely.
Clean the mating surfaces on both the transmission and the pan with a solvent.
Install a new gasket or seal, ensuring it is properly seated.

4. Reinstall Transmission Pan

Tools Required: Torque wrench.
Reattach the transmission pan and tighten the bolts to the manufacturer's specified torque (consult service manual for exact value).
Ensure no debris is caught between the pan and gasket.

5. Refill Transmission Fluid

Use a funnel to pour the appropriate amount of new transmission fluid into the dipstick tube (consult owner’s manual for specific type and quantity).
Start the engine and allow it to reach operating temperature.
With the vehicle in park, check the fluid level and add more fluid if necessary.
