2000 GTs come stock with 3.27 gears. After dynoing my car I had a tuner tell me that my speedometer was wrong and that I had 3.73 gears. When I had the car retuned the new tuner said he had to adjust my speedometer because it looked like I had 3.55 gears. I jacked up the car and turned the rear wheels. It looked to me like I had 3.27 gears. As it turns out, I have 3.27 gears. Whoever put in the white face gages put the speedometer needle in the wrong place.
Lift up the rear of your car and put a caulk mark on both the tire and the driveshaft. Turn the tire one complete revolution and count the number of times the driveshaft goes around. If it goes around 3 1/4 turns then you have 3.27 gears.
