Experts, I need your opinions! I did 2 D&F back in August and got the third one done last week on my 2015 Ford Edge. Long story short, at first drain (13k miles) I found 2~3 curved metallic derbies about finger nail size and some very small metal bits in the drain pan. Fast forward to last week, I did another D&F at 15k (2000 miles later) and I found one tiny gold color flake in the drain pan but thats it. it was pretty clean on the 3rd drain. I already scheduled with service to have it take a look but due to Hurricane it got postponed till later this month. I would like to hear your thoughts on this. Transmission shifts ok for the most part except having a small flare (500rpm went up to 1000rpm) when down shifting from 2nd to 1st. Much thanks in advance!
