[QUOTE="Husky44, post: 13039002, member: 142759"] Did the install of my 3.73s, and [URL="http://www.svtperformance.com/forums/2013-shelby-gt500-413/932650-3-73s.html#post13018547"]love them[/URL]. Took the car to local dealer to have them reset my computer so that the speedo reads accurately. Dealer's computer indicates option to change gear ratio to 3.73, but when he does, it doesn't change the speedo reading. Tried multiple times, before he sent request to Ford Hotline Assistance. Their response: [INDENT]Unfortunately the Hotline is unable to assist you with this modification as it isn't supported, and thus it is the Hotline's recommendation that the vehicle be returned to factory condition. Altering the tire or axle configuration from the factory isn't a recommended or supported modification by Ford or the Hotline. The tire size and axle ratio cannot and should not be changed to address a speedometer accuracy concern as a result of aftermarket modifications. [/INDENT]I'm going to contact SVT next, and if they're no help, then Ford Customer Care. This is a bone stock car, with a factory tune, no mods other than 3.73s, which shows up in the shop programmer as a viable selection for rear gears. Gears are Ford Racing gears--an option they offer for this car. Needless to say, I'm not real pleased with Corporate Ford right now. I started a new thread to keep folks informed. I'll update this as I learn more. This is definitely a great mod for the car; if I have to go to an aftermarket tuner to fix my speedo I will, but there will be plenty of info in Ford's records that I was forced to do so by their lack of support.
