I love the box but think the drivetrain is junk. I have the manual there is a lot of drivetrain whine in 1st and 2nd gear upon acceleration. I first thought it to be the transmission. However if I drive to 45 mph and put the tranny in neutral and coast to a stop it is actaully the differential. Try this if you have a manual. I am going to test drive another if it is inherant with the car I am going to dump it. It is really annoying when you are in traffic speeding up and down. I should have kept my Focus ZX5 with the 2.3l
