Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool before proceeding with any work on the transmission.

2. Drain and Replace Transmission Fluid

Tools Required: Socket set, fluid catch pan, funnel, 8mm socket, torque wrench.
Locate the transmission fluid drain plug and remove it using an 8mm socket.
Allow the old fluid to completely drain into the catch pan.
Once drained, clean the drain plug and replace it, using the torque specifications provided in the owner's manual.

3. Replace Transmission Filter (if applicable)

Remove the transmission pan by unscrewing the bolts with the socket set.
Carefully lower the pan and remove the old filter.
Install the new filter, ensuring it is securely in place.
Clean the mating surface of the transmission and the pan.

4. Refill Transmission Fluid

Reattach the transmission pan and secure it with the appropriate torque specifications.
Use a funnel to refill the transmission with the correct type of fluid as specified in the owner’s manual.
Start the engine and allow it to run for a few minutes while checking for leaks.

5. Final Check

With the engine running, cycle through the gears (P, R, N, D) to circulate the new fluid.
Check the fluid level again and add more fluid if necessary.
