I have a 2011 Limited w/ the 5.7L and have noticed that when cruising at 75-80mph and then punch the accelerator to pass, the downshift seems very rough. Is this normal? Would the TSB 18-035-11 correct this problem?
Had the transmission flash done and I am a happy camper Much smoother shifts and feels like there is definitely more power available. Dealer knew nothing about the TSB but was more than willing to provide the update.
