I think the 9 speed is here to stay. It improves gas mileage in these bigger sized engines and that is what the government is after. I think with time and experience, FCA and ZF will continue to improve them. While I will not be surprised if my 2015 tranny comes down with the flu some day, so far even after 42,000 miles on it, its been very healthy.
