Wish they would just use the same ratios as found on the manual box, but apparently that would have cost more as the current auto is a (slightly modified) off-the-shelf part.

Also, Sport-Tech is right, the gearing is more noticeable in higher gears, but in the lower gears, not as much. The lower gears are the gears you will use on a track 99% of the time and the gears that matter for performance. I think the 5-60 (no launch) motortrend test between the two is telling, only one tenth of a second difference in acceleration with no launch required. But yes, I did say 2-6 would be nearly identical and I should have said "2-4 will be very similar".

this is good to know,because the seat of my pants (where it counts) tells me the car's got plenty of "juice" from a dead launch,and i experienced no "dead" spots as the revs climbed.for some reason,i really liked the rev matching
as you down shift. THIS car does not suffer with this auto tranny.
