Unforgiven -

I had no idea about the joint venture with Ford. I don't think this will add to your knowledge, but I googled "ford transmission 6T70/75 gear ratios" and found some more URLs to read :

GM to Incorporate Innovative Transmission in 2007
GM plans to offer more 6-speed trannies than any other - AutoSpies Auto News
GM-Ford 6-speed automatic transmission - Wikipedia, the free encyclopedia
Code:
Gear ratios:
1       2       3       4       5       6       R      Final drive
4.484   2.872   1.842   1.414   1.000   0.742   2.88   2.77, 3.16, 3.39
The Aura *appears* to be setup for the tallest geared configuration.
