I'm new to the forum. I've read a fair amount of transmission performance complaints (slow to downshift, lags etc.)

The dealer wouldn't tell me the tsb # they applied. All they said is the car needed an ecu update.

I wish I did this a year ago. Car shifts quickly! I did do the ecu reset when I bought it to improve throttle response.

Maybe this info is widely known. I thought I'd post anyway in case someone could benefit from my experience.

Welcome to the forum! And thanks for sharing...the info isn't on your receipt?
