3.7L V6 Mustang MT-82 to T56 Magnum XL Conversion 

2010-14 Mustang Magnum XL upgrade packages by Modern Driveline, If you’re driving a 2011-14 Mustang with the 3.7L DOHC V-6, we’ll bet you’re frustrated with sloppy shifts, gear clash, disappointing acceleration, and durability issues.
Despite overall world class Mustang build quality, the factory’s Getrag MT-82 six-speed just isn’t up to the job in performance. 

This is where MDL steps in.  We rolled up our sleeves and developed a complete 3.7L V6 Magnum XL double overdrive close ratio six speed package from front to back.  Starting with our billet steel flywheel and Superior Kevlar clutch, it can handle all the power supercharged 3.7L can put out and be fun to drive everyday to work.

MDL was the first to receive and develop the Magnum XL. When Prestolite blew up its MT-82 amid a fury of wide open throttle performance and acceleration, it looked to Modern Driveline, for solutions to its drivetrain issues.  Before anyone else could get their hands on the then new Magnum XL we developed a complete TREMEC T-56 Magnum XL conversion for Prestolite’s Mustang demonstration vehicle, getting these folks back on the road in short order.

5.0L GT and Boss MT82 to T56 Magnum XL Solution

It is challenging for us at Modern Driveline to understand the engineering logic behind the Getrag MT-82 six-speed transmission in the 2011-2014 Mustang. The factory installed MT-82 employs a semi-remote shifter attached to the transmission tunnel tied to the transmission via a shifter rail that, at best, delivers sloppy shift performance with the luster of a broomstick in a barrel. Notchy shifting. Locked out gears. And the sinking sound of a failed gearbox.

If you’re going to hit the road with a bang-shift attitude for a little canyon cutting, you want a confident feel in your hand.  This is why Modern Driveline offers you a suitable drop-in replacement designed and engineered for a brute Mustang kind of day — the Modern Driveline/TREMEC T-56 Magnum XL double overdrive six-speed manual transmission. The MDL 2010-14 Mustang Magnum XL upgrade package is an easy weekend install because Modern Driveline has thought of all of it for you.
