Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is on a level surface and securely lifted using jack stands.
Disconnect the vehicle's battery for safety.

2. Drain Old Transmission Fluid

Locate the transmission drain plug and place a drain pan underneath.
Remove the drain plug with a socket set and allow the fluid to fully drain.
Dispose of the old fluid according to local regulations.

Identify the transmission pan, typically located on the bottom of the transmission.
Remove the bolts securing the transmission pan using a socket wrench.
Carefully lower the pan and replace the old transmission filter with a new one, ensuring proper alignment.
Clean the mating surfaces of the transmission and the pan.

4. Install New Transmission Fluid

Reinstall the transmission pan and torque the bolts to the manufacturer’s specifications (usually around 8-12 lb-ft).
Refill the transmission with new, manufacturer-recommended transmission fluid using a funnel in the dipstick tube.
Check the fluid level with the dipstick and add more fluid if necessary.

5. Final Steps

Reconnect the battery and start the vehicle.
Allow the engine to warm up and cycle through the gears to circulate the new fluid.
