Summary
Some 2018-2019 Mustang vehicles equipped with a 5.0L engine and a manual transmission may exhibit an inability to drive the vehicle in first and/or second gear. This may be due to a broken 1-2 shift fork. To correct the condition, follow the Service Procedure to replace the 1st/2nd shift fork, the mainshaft 2nd gear, and the 1st/2nd gear synchronizer hub and sleeve.
