So I finally got around to changing out transmission oil. After draining the oil I’ve come to conclusion that it’s absolutely shit oil they put in the transmissions. I have 12k miles on mine and it came out like water. No wonder why these things are failing so early. I started to get the rumble noise and also noticed 3rd gear was becoming more notchy to shift into. I bought BG Syncro Shift 2 and it is night and day. It shifts like butter again and I haven’t heard any rumbling noise yet. Will have to see on a cold start tomorrow morning if the noise is gone… fingers crossed. I understand the reason for the light weight oil for the transmission due to hitting those mpg numbers, I think Ford needs to re-evaluate the oil used. I’ve never had a manual gear box with this thin of an oil .
