Hello everyone! I own a 2017 Mustang V6 with 90,000 km and a 6-speed automatic transmission. I've been using it for a month and it's perfect on the road, but it has two issues.

The first one, which is less concerning, is a "metallic rubbing" noise coming from the transmission when it's under stress, when downshifting with engine braking, or when the car is pulling. I thought it might be the torque converter, but it shifts well and never slips, so I'm not sure. I'll be doing a transmission fluid change soon and I hope that will fix it.

The second issue I noticed after getting the alignment and suspension checked is a very small leak of some fluid from under the transmission (it doesn't leave stains in the garage, so I think it might only leak while driving, maybe under stress). I can’t identify the fluid; it just looks very clean. Following the "trail," it almost seems like it's coming from a manifold.

One more thing to mention: sometimes the transmission feels a bit jerky when it's in D (Drive) and not in S (Sport) while trying to shift at low RPMs, but I read that this is normal.

I’ll be taking it to my trusted mechanic next week, but I'm trying to gather as much information as possible beforehand. Thanks a lot, everyone! (All fluid levels are excellent, they warm up properly, and the car has no other symptoms).

So did you have your transmission fluid changed yet? Has your mechanic looked at this yet? Here's a bump
