The gears are the same. The main differences is the tko has a 26 spline input shaft as opposed to the 3550's 10 spline. The tko also has a 31 spline output shaft as opposed to the 28 spline on the 3550. I understand how you feel since you have a near brand new clutch already in the car. Also, the t5's usually have a taller 2.97 first gear versus the steep 3.27 of the tremecs. A new world class t5 or t5z would run just about the same as that sale price on the 3550 so the 3550 is the better deal. If you need a tranny for more power, tremec also makes the TKO which is rated ar 425 and the TKO II which is rated at 475.
