No. But it's perfectly safe to replace the 3.31's with a set of 3.55's, since those are standard issue in the EcoBoost automatic and both the GT manual and the GT automatic.Thx !
It's a pitty the benefits between the different gear sets aren't mentioned..any idea in numbers ?
In the US cars the 3.55 gears are part of the Performance Package.
