Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Drain Transmission Fluid

Tools Required: Socket set, drain pan.
Place the drain pan under the transmission pan and remove the drain plug or pan bolts.
Allow the old transmission fluid to fully drain into the pan.

3. Replace Transmission Filter

Tools Required: Socket set, torque wrench.
Remove the transmission pan by unscrewing the bolts.
Carefully take out the old filter from the transmission.
Install the new transmission filter and ensure it is secured properly.

4. Clean Transmission Pan

Remove any old gasket material from the transmission pan and the mating surface on the transmission.
Clean the pan thoroughly and inspect for any metal shavings or debris.

5. Reinstall Transmission Pan

Install a new gasket on the transmission pan.
Reattach the transmission pan using the torque wrench to tighten the bolts to the manufacturer’s specified torque settings.

6. Fill Transmission with New Fluid

Tools Required: Funnel, new transmission fluid (check the owner’s manual for the correct type).
Use a funnel to fill the transmission with new fluid through the dipstick tube or designated fill port.
Start the vehicle and cycle through the gears to circulate the fluid, then check the fluid level again and top off as needed.
