Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues during the repair.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan and allow the fluid to completely drain.

3. Inspect and Replace Filter

Remove the old transmission filter from the valve body.
Clean the valve body surface thoroughly.
Install the new transmission filter, ensuring it is seated properly.

4. Reassemble Transmission Pan

Clean the transmission pan and remove old gasket material.
Apply a new gasket or RTV sealant as per manufacturer specifications.
Reattach the transmission pan with the appropriate torque specifications for the bolts.

5. Refill Transmission Fluid

Use the recommended transmission fluid type.
Reconnect the battery.
Start the vehicle and let it idle, shifting through all gears while monitoring the fluid level.
Add fluid as necessary to reach the proper level.
