Solution

1. Preparation

Tools Required:
- Socket set
- Torque wrench
- Screwdriver set
- Drain pan
- Funnel
- Clean rags
Ensure the vehicle is on a level surface and safely supported on jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using the socket set.
Carefully lower the pan and allow the fluid to drain completely into the pan.
Inspect the old fluid for metal shavings or debris, indicating internal wear.

3. Remove Old Filter

Once the pan is removed, locate the transmission filter.
Remove any bolts securing the filter to the transmission using the socket set.
Pull the old filter down and out of the transmission, ensuring that the filter seal comes off with it.

4. Install New Filter

Apply a thin layer of transmission fluid to the O-ring of the new filter.
Insert the new filter into the transmission, ensuring the seal fits properly in the bore.
Secure the filter with the bolts and tighten to manufacturer specifications (usually around 8-10 Nm).

5. Clean and Reinstall Pan

Clean the transmission pan thoroughly to remove any old gasket material.
Inspect the pan for damage; replace if necessary.
Install a new gasket on the pan or apply gasket maker as per specifications.
Reinstall the pan and tighten bolts in a crisscross pattern to the specified torque (typically around 10-12 Nm).

6. Refill Transmission Fluid

Locate the transmission fill plug and remove it.
Using a funnel, refill the transmission with the appropriate type and amount of new transmission fluid (check specifications, often around 7-9 quarts).
Start the engine and allow it to reach operating temperature, then check the fluid level again.

7. Final Checks

Reconnect the negative battery terminal.
Check for leaks around the transmission pan and filter.
Test drive the vehicle to ensure proper shifting and operation.
