Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a level surface and securely supported with jack stands.
Disconnect the battery to prevent electrical issues while working on the vehicle.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket wrench and carefully lower the pan to drain fluid.
Inspect the pan for metal shavings or debris which may indicate internal damage.

3. Replace Transmission Filter (if applicable)

Remove the old transmission filter if equipped.
Clean the filter mounting surface and install the new filter, ensuring it is seated properly.

4. Reassemble Transmission Pan

Clean the old gasket material from the transmission pan and the mating surface.
Apply a new gasket or sealant as per manufacturer specifications.
Reinstall the transmission pan and torque the bolts to the specified torque values (refer to the vehicle's service manual for exact specifications).

5. Refill Transmission Fluid

Use a funnel to refill the transmission with the appropriate type and amount of fluid as specified in the owner's manual.
Start the engine and allow it to reach normal operating temperature.
With the engine running, cycle through all gears and check the fluid level again, adding more fluid if necessary.
