I am interested in seeing what a tune can do in a Fusion Sport as the current performance 93 octane tunes for a F-150 with 2.7TT sees gains of 60HP and 100ft/lb torque at peak levels but does anyone know how much torque the 6F55 transmission can take. I read that the transmission was fortified but I worry that at the current 380ft/lb being listed by Ford (or 400 ft/lbs in the Lincoln counterpart MKZ using the 3.0TT engine - both using what I assume is the same 6 speed) that there may not be much left with causing damage. I hope that Ford has made this transmission capable enough that we may be able to use a nearly 500ft/lb Fusion - this would be a beast of a car that no one would ever see coming>:).

My only reference to the transmission being used in the Fusion was posted by MotorTrend in their 2017 Ford Fusion First Look review.

This is why I'll probably wait a year or two before I consider a tune to let everyone else crater their drivetrains. I remember the sorry transmission in my old '93 Taurus SHO as well as the made-of-glass drivetrain in the 2012 Hyundai Genesis Coupe 3.8 Track Edition. The sounds that torsen rear diff made toward the end.... :crying:

Well I have been looking for a solid spec but haven't found one yet. But, if we follow Fords normal transmission nomenclature what we have is:

6 = 6 Speed
F = FWD
55 = 550 Newton-Meters or 405 ft-lbs of torque (downstream side of the torque converter)
