Description

Beginning with the 2011 model year, Ford debuted the 6R140 six-speed automatic that really shined with its inherent ability to hold up to plenty of abuse and miles. That said, with auto manufacturers striving for fuel economy coupled with huge power numbers, six gears flat out wasn’t cutting it. Ford instead opted for a ten speed Torqshift that’ll ensure you’re constantly in that sweet spot of torque for the ultimate pulling experience. With ten gears on tap, you’ll never be light footing the throttle going up an 8% grade with 15k behind you, trying to maintain your current gear to avoid a massive drop or spike in RPM. Nope, you’ll have minimal changes in RPM’s throughout, which will aid in maintaining boost and overall torque throughout. Oh yeah, and because of this, fuel economy gets a nice bump, as well.
