Solution

1. Preparation

Gather tools and materials: socket set, wrench set, transmission fluid, funnel, fluid catch pan, and safety gloves.
Ensure the vehicle is parked on a level surface, and the engine is off and cool.

2. Drain Old Fluid

Step 1: Place a fluid catch pan underneath the transmission pan.
Step 2: Remove the transmission pan bolts using the socket set, and gently pry the pan loose to drain the fluid completely.
Step 3: Inspect the pan for metal shavings or debris, which can indicate internal damage.

3. Replace Transmission Filter (if applicable)

Step 1: Remove the old transmission filter (if equipped) by disengaging any retaining clips and pulling it straight out.
Step 2: Install the new transmission filter, ensuring it is seated properly.
Step 3: Replace any seals or O-rings as necessary.

4. Reinstall Transmission Pan

Step 1: Clean the surface of the transmission and the pan to remove old gasket material.
Step 2: Apply a new gasket or RTV sealant as recommended by the manufacturer.
Step 3: Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications.

5. Refill Transmission Fluid

Step 1: Using a funnel, pour the appropriate type and amount of new transmission fluid into the dipstick tube.
Step 2: Start the engine and allow it to reach operating temperature.
Step 3: With the vehicle in park, check the fluid level and add more if necessary until it reaches the proper level.
