I just had the transmission TSB fix done on my Max. They did the solenoid and TCM. I have noticed a good improvement but it is not as much as I was hoping for. My expectations were probably too high. Anyway, it is much improved and I am happier with it. If I need more improvement, I'll have to go for a valve body upgrade (not sure). Anyway, just wanted to share my impression of this fix. Good, but would have liked more.
