ive never changed the trans fluid ever i dont think. thats no good, and i really dont want to do a manual conversion, i drive my car everyday, although, i do like to go to the track, and test out my car, i just want to turbo my car, or maybe just do some N/A thats why i said turbo or N/A, cause its auto, and i drive it all the time, or maybe i should just get another car, doh.
