Hi all, 1st time. Suggestions please. I have a 2016 Ford bmax Titanium ecoboost bmax approx 34000 miles and majority of milage is local 2-4 miles, sometimes 23mis x2. The car has been serviced/Yr but now l am starting to hear a slight whining noise from gearbox area. I was wondering g about the gearbox oil and it's frequency for being changed, also, sometimes in the hot weather the gears have been awkward and feeling slightly sticky when being selected. I wonder if the GB oil could be low. Any thoughts would be appreciated. Thks
