i have the famous a604 transmission transmission was rebuilt about 50,000 miles ago everything was fine up until a few days ago when it dropped into limp mode. brought it in and had a metal fatigue failure with the high gear. They replaced two parts inside and everything is fine other then a small leak from the axle seal but that is not what i am worried about. I am worried that they did not use the right fluid i know it calls for ATF 3 or mopar 7176 but i don't know what they put in. Is there any way i can tell from the color or anything. It is a very light red color or almost a light pink color. Should i be concerned?
