5.0L Mustang GT  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 2015-2018 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.
