I would infer that it is the same Getrag transmission that is used in the 260 horsepower Cobalt-SS.
I don't have any experience with aeromodding, yet. On the last time I change oil, I did it myself and used Mobil 0w-30. ($25 / 5 quarts) Mobil says you can save a few tens of dollars per year with the high efficiency synthetic oil.
I bought 12.6 pound aluminum alloy wheels at
Discount Tire Direct for $100 each. Saved 5 pounds/wheel and saw an immediate 2 mpg difference. I had to buy TPMS modules, too. Maybe you want new low rolling resistance tires. There are some new designs out there, including one by Goodyear.
