Not really, trans was only used in 2 formats to my knowledge, 1st gen gt, and 1st gen probe with the 3.0. The 3.0 has a better gear set, but not much taller. 1st and 5th are the same ratio, and the final is a 3.85 vs the turbos 4.11, the other 3 gears are slightly different to the turbo set, so slightly taller overall, but not much. Overall the 3.0 gears are better imo, as give more even rpm drops between shifts.
