To perform a treatment with a friction modifier for the transmission fluid in this vehicle, watch the video and read the information in this tutorial. Once the vehicle is on the lift, locate the transmission fluid drain plug, and just above it is the fill plug that you will unscrew.

Wait for some of the lubricant to flow out from the upper plug. Then, take the additive and use a pump to refill the fluid through the fill plug.

After adding about half of the volume in the bottle, screw the fill plug back on.
