I paid the local Acura dealership to change my transmission fluid at 60K, however, I have had a couple of oil change franchises state that I still need to have this done. That showed me the fluid on the dipstick placed on a white towelette. It appeared to be a rusty brown with a hint of purple. I know that most automatic transmission fluids are pink to magenta in color. Did they just park my car in the rear and call me later in the day? How can I know if they have actually did the work that I paid for? I now have 68K on the Acura TL.
