Hello dhuang,I've had a "transmission fault" happen twice so far, and the car has always been in Dynamic + Manual when it occurred. 38k miles on a 2015 LE with an Alfaworks Race ECU and supposedly the previous owner did the transmission flash.
Still trying to figure out how to consistently reproduce the fault.
We certainly understand your frustrations with your transmission concern. Please feel free to let us know via private message if you decide to address this with your dealer and we will gladly assist you during that process.
