I have a new 2008 GT500 with about 3200 miles. I get clutch chatter sometimes when releasing the clutch in first gear with little power. Could this be a clutch issue or just the case that these clutches need to be pedal dumped or engaged quickly and do not like rubbing or getting stick hot is stop and go traffic?
I am also having a cold air induction kit, blower pulley and dyno tune added (525RWHP Total) and my mechanic mentioned that most GT500 owners are changing the axle gear to a 3.73 vs. the stock 3.31 to lessen the clutch stress. This is also done on the GT500KR. Do you think I will have clutch issues if i do not change the axle 3.31 gear? Also with the added horsepower mods, do you think Ford will warranty the clutch?
I also have experienced a faint rear axle harmonic noise at about 3k rpm and the dealer advised that the axle pinion is breaking in, yet sometimes seams to be loader at launch. My mechanic mentioned that it could be a poor alignment issue with the axle gears from the factory. Has anyone experienced this same rear axle noise and do you think it is a problem?
Thanks for your help!
Mike
