Some of the reported issues occurred when drivers were merging into high-speed traffic or while turning against traffic. According to an article in The Sacramento Bee, Ford planned to fully cooperate with the review. Unfortunately, this isn't the first time we've heard of complaints regarding manual transmissions on the newer Ford Mustang. It seems quite a few folks have experienced issues. Reader Gregory Camacho said, "I have a 2012 Mustang GT with only 989 miles on the clock, and I have experienced shifting problems. Not much to say about cold climate because it has not been cold at all in Texas, but the shifting from first to second is rough and notchy. It's almost like there is a missing part or gear that catches. While stopped at a light and attempting to move forward, I've had to shift into third gear and slowly move up, because the car refused to go into first or second gear. I hope that Ford fixes my problem and everyone else's." Another reader, Kevin J., said, "I've got a 2012 Mustang GT with the 6-speed manual transmission. Mine has had problems with not locating gears, going into reverse when I put it into first-while taking off from intersections, and occasionally grinds second and third gears. It's been doing this from day one." He added, "I originally took it to the dealer at around 800 miles, who sent me away saying that they need to bring in the 'Ford Engineer'- which took another 6 weeks. Upon him driving it with me in the passenger seat, he revved it up in third gear, and while attempting to get into fourth, grabbed second, and locked up the rear end-flat-spotting my tires, and doing who knows what else to the car. When we got back to the service drive, I saw a lot porter get in an attempt to move it forward. He put it in first, and promptly went in to reverse, stopping maybe two inches from hitting the car behind him." It should be noted, there is a feature found on automatic V8-powered Mustangs that forces the transmission to shift directly from first to fourth gear under light throttle application. This feature was designed to increase fuel efficiency during the EPA fuel economy testing procedure and cannot be turned off.
