Just purchased a new '04 GTO with the auto tranny. For some reason this transmission seems to shift much less "agressively" than the automatic in my stock 2000 Trans Am. If I floor the accelerator in the GTO from a rolling start at about 35-40 mph (with the traction control disengaged), the downshift seems to be only from 4th gear to 3rd gear. It does not throw you back in the seat and seems to accelerate only at a moderate rate until the RPMs get back up. My Trans Am will downshift to 2nd gear, chirp the tires, and take off like a scalded dog from that speed. Has anyone else experienced this with the auto transmission, or is this just the way it is? I've only got about 400 miles on the car so far and find this to be pretty disappointing.
