Thats basically what I was going to say. Some small tuning and you can have that auto shifting hard and quick(don't take that out of context). My friend has a tuner for his auto cobalt and it shifts quickly, stays in gear longer, and the instant you lay down the pedal if you were cruising in OD, it shifts back down quick!
