Jw23 posted a topic in 3.7LHello all, Had my MKX in to an independent shop today for an alignment, and they noticed that the trans fluid was pretty dark during the vehicle inspection. I verified it when I got home and noticed the same. I bought it at ~49,000 miles, and it currently has 89k on it. To my knowledge, the fluid hasn’t been changed to this point, and I’m not sure whether I should go with a transmission flush or just a simple drain and fill. I’m finding conflicting answers for the 6F50, so I was wondering if any of you have experience on this front. Any advice is appreciated, thanks!
