At the moment, my research shows that the GT's come with 3.31 gears from factory. There is an option for Premium GT's with Manual transmissions to swap the 3.31's with 3.55's.
I know the manual trans is rated for better gas mileage, and had assumed that the auto's had different gearing. However, I've just found some information that discusses the specific ratios for each gear in each transmission. From that information, I gather that any gearing differences between the Auto and the Manual are caused by the transmission, not the rear end.
All Ford literature that I find indicates that the 6 bangers, 4.6s and Shelby's come with 3.31 gears.
Here are the transmission ratios as shown on Automotive.com: 44K 5-Speed Manual Transmission
Manual five-speed transmission with shift lever on floor, 3.340:1 first gear ratio, 2.000:1 second gear ratio, 1.320:1 third gear ratio, 1.000:1 fourth gear ratio, 0.670:1 fifth gear ratio and 3.380:1 reverse gear ratio Tremec 3650; Standard transmission; Excludes: [44L] 4-Speed Automatic Transmission

hey there! can you remove hte tag on your diff cover oneof two tags tell you the gear ratio and wether its a limited slip or an open carrier usually for a gt mustang would be 3.73 ratio but it changes if automatic or standard trans,....
3.31
Should be 3.27
I had a 1991 Ford Mustang 5.0 L - LX - automatic , and it had 2.73 's
The axle ratio on a 1989 Mustang was # 3.45:1 standard four # 3.73.1 optional four # 2.73:1 standard GT # 3.08:1 optional GT
I believe that is 2.73 ( axle code " M " )
yes, its a possible but it depends on the drive train, your gear ratio, and if its an automatic or manual.
The gear ration on a 1988 Mustang is # 3.45:1 standard (four) # 3.73:1 optional (four) # 2.73:1 standard (GT) # 3.08:1 optional (GT)
Probley not a stright stick trans. is geared different then a automatic. But the rear end gear ratio. could very well be the same. Not sure I understand your question.
The gear ratio for a 1988 Mustang is 3.45:1 on a standard (four) and 3.73:1 optional (four)
The compression ratio for the 1995 Mustang is: 9.0:1
