Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical issues.

2. Drain and Replace Transmission Fluid

Tools Required: Socket set, fluid pump, transmission fluid, drain pan.
Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket wrench and carefully lower the pan.
Allow the old fluid to fully drain into the pan.
Inspect the pan for metal shavings or debris; clean the pan thoroughly.

3. Replace Transmission Filter (if applicable)

Remove the old transmission filter (if your model has one) and discard it.
Install the new transmission filter, ensuring it is seated correctly.

4. Reassemble Transmission Pan

Place a new gasket on the transmission pan.
Reattach the transmission pan and tighten the bolts to the manufacturer's specified torque settings.

5. Refill Transmission Fluid

Use a fluid pump to fill the transmission with new, manufacturer-recommended transmission fluid.
Check the fluid level using the dipstick and add fluid as necessary until it reaches the full mark.

6. Final Check

Reconnect the battery.
Start the engine and allow it to warm up.
Shift through all gears and check for leaks around the transmission pan.
