[QUOTE="jmatero, post: 10343742, member: 113572"] I disagree about there being nothing mechanically wrong with the drivetrain. There are close to 500 posts on this topic in the past 7 weeks at allfordmustangs.com with Ford reps monitoring and contacting owners (including me) regarding two known mechanical problems with the drivetrain. My car has been used by Ford to test a number of solutions... and is now being used to test what will most likely be an official fix. The last of the new-design parts arrived today and the car gets EVERYTHING between the crank and driveshaft swapped out with Job2/2012 parts. What do we know currently? 1. The majority of clutch issues on pre 09/2010-built Mustangs are a result of pressure-plate bolts backing out and not allowing full disengagement of the clutch. This eventually shears the flywheel dowels, destroys the clutch, and causes premature wear of the synchronizers. This is a known issue and the solution is replacement of the damaged components, installation of 6 redesigned pressure plate bolts, and a new reassembly procedure. There are few if any reports of clutch engagement issues on cars with the new-design pressure plate bolts. 2. Ford redesigned the synchronizers in the MT82. They began using the updated parts on August 24, 2010. There are few if any reports of gear grinding being reported by owners who's cars have these new synchros. The pressure plate bolts, synchronizers, and Reverse (input shaft) on Job1 cars are proving to be "Mechanically unsound". There are HUNDREDS of posts on this... and the symptoms all start the same way: Pressure Plate Bolt Issue: Early symptoms are a change in the engagement point of the clutch. Then, it becomes difficult to modulate the clutch. Smooth progressive launches in 1st become impossible. Eventually, gears begin to grind as shifts are taking place with the clutch partially engaged. In the final stages, the clutch fails completely. Synchronizers: Early symptoms are grinding during cold shifting from 1-2 and 2-3. Eventually, grinding occurs on upshifts (to any, some, or all gears) irregardless of ambient temperature, or whether car is warmed up or not. These are the facts. If you are not experiencing these issues, I'm very happy for you and you should feel comforted knowing that if they DO appear in the future, there will be a fix. I can see how... if you only read this particular thread... you would come to the conclusion "there was no issue". I would suggest you read all 600 posts on THIS thread to gain a better perspective of the major clutch and transmission issues so many of us a dealing with: [url=http://www.allfordmustangs.com/forums/2011-mustang-talk/268693-official-2011-mustang-manual-transmission-rough-shifting-thread.html]Official 2011 Mustang Manual Transmission Rough Shifting Thread - Ford Mustang Forums[/url] [/QUOTE]
