I hear they are having problems with their 8 speeds, so I imagine the 9 speed will probably have it's issues too.
I own a GM 6 speed (Silverado), I mean I like it...no issues yet, but even the 6 speeds have issues.
I have owned an 8 speed Airens (Lexus LS460) and that was great, absolutely love what these 8 plus speed units can do in terms of fuel economy, but be warned, they have had their issues across the board from all manufacturers. And I have spoken to people who the manufacturers buy them from (the companies that make them), they say...don't blame us, blame GM, blame Chrysler...we start out with our set of specifications and they come back and want it done cheaper, and that's the problem...manufacturers don't care as long as these things can last until the warranty period is up. But this company actually told me...the 8 speed we sold Chrysler is not the same as the 8 speed we sold BMW (or at least I think it was BMW, can't remember now, but the failure rate was so much higher on the Chrysler).
