For the 2011 model year, Tremec has been ditched as the supplier of the T5 and TR-3650 manual transmissions in the Mustang V6 and Mustang GT in favor of Getrag. The MT82 and MT82-D4 as the six-speed stick shift that has been plagued with problems ever since, and some customers have had enough.

Three so-called generations of the MT82 rolled out since the 2011 model year S197. The Gen 3 features the D4 suffix, launched for the 2018 model year S550 facelift with improvements such as upsized synchronizers for the first through fourth gears. The revised synchronizer cone angles and tooth geometry, new power flower architecture and shift inertia, as well as a few more upgrades haven’t solved the problems over which Ford has been sued by disgruntled owners.
“Gregorio v. Ford Motor Company” is how the class-action lawsuit is called, filed with the U.S. District Court for the Eastern District of Michigan on May 26th, 2020. Transferred to the Central District of California, the lawsuit mentions slipping, jerking, harsh engagements into gear, clashing gears, premature wear, and premature failure of the MT82 and the third-generation MT82-D4.
The plaintiffs are trying to make a case for switching from Tremec (and Borg Warner) to Getrag “to save money,” adding that the six-speed manual was originally designed for small cars with less horsepower and torque. If you look through the Ford Motor Company’s technical service bulletins from the 2011 model year onward, you know that something is amiss with the MT82 box.
In September 2010, TSB 10-19-4 highlighted “a clutch pedal stayout condition” on 2011 Mustangs with “10,000 miles or less” on the odometer. TSB 18-2267 suggested that some 2018 to 2019 Mustangs “may exhibit an inability to drive the vehicle in first and/or second gear” over “a broken 1-2 shift fork.”
Adding insult to injury, even the National Highway Traffic Safety Administration conducted an investigation into the MT82 in 2011 after receiving more than 360 complaints. However, Ford has blamed “abusive” owners for the transmission’s wear and tear and ultimate failure for 10 years and counting.
