3rd gear

  1. 2005-2010 Mustang GT Tech
    I just bought a '09 GT... got about 4200 miles on it. Whenever i shift, i can feel the syncros working and stopping me from grinding the gears except when i try to downshift to 3rd. Whenever i try to do that i feel the gears start to grind. It's been doing this since i drove it off the lot...
