Clutch/trans Tsb Released

TSB
08-16-4 SHELBY GT500 - CLUTCH DRAG

Publication Date: July 28, 2008

FORD: 2007-2009 Mustang


ISSUE:
Some 2007-2009 Mustang Shelby GT500 vehicles may exhibit the following clutch/transmission symptoms: hard to disengage or engage 1st and reverse, hard to shift any gear, gear grinding during shifts any gear, vehicle creeps with trans in gear and clutch pedal fully depressed without brake pedal application, clutch slippage in gear with clutch pedal released, hiss noise with clutch pedal fully depressed (hiss on clutch pedal release is normal for GT500 clutch material). These symptoms may be due to flywheel distortion caused by excessive heat build-up during unique traffic conditions (example: severe stop/go urban driving). The distortion of the flywheel may prevent complete disengagement of the clutch. The system is designed for performance driving conditions.

Re: Clutch/trans Tsb Released

Repair and not replace seems to be the new order of business. Some of us were fortunate enough to keep the original tranny as well as receive a replacement. Torque specs are back to the original due to the change in the flywheel. The original flywheel was experiencing wharping issues and the temporary fix was to lower the torque specs on the clutch. I also like the idea of the change in the pilot bearing, something I noticed on milezperhour's photos, which I commented on in his thread. His input shaft had quite a bit of rust and the needle bearings left rust marks on the tip of the input shaft.

Re: Clutch/trans Tsb Released

Hmm... I have a really stupid question.............

"The clutch fully depressed"

Re: Clutch/trans Tsb Released

So does this mean the dealer will fix it under warranty or what is the steps to get this taken care off. The last time I called the local dealer they acted as if they never heard of this before. Maybe they have maybe not. And can you take it to any dealer SVT to do the repair. I bought my car 3 hours away but have a dealer 10 minutes away ?

Thanks,
Bill
