Well, it is essentially the same trans as the 98-02 F-Body T56. I don't know the physical differences but, the F-Body has a torque arm, GTO does not. So that aspect is different. They may use different gear ratios and or different input shafts and output shafts. So, just do your research. The later T56's use an internal concentric slave cylinder instead of an external slave like the earlier 93-97. Which makes it a bit of pain to change if it starts leaking, so I'd urge you to replace it while it's out before installing for good measure. Doubt you'd like to pull it twice. =)
