"When pulling away from a stop, up to about 45mph, if I am just accelerating gently, at 1/3 or less throttle, the car seems to lunge and surge, maybe those are better words than "hesitation". I will try a search for those words."

I have a 2006, 5.7, and the 3 to 4 shift has the lunge-surge. It will give a code from time to time, which is "bad gear ratio." The Dealer has replaced the transmission, but it is still the same. The 3 to 4 shift at 31 MPH still has the lunge or surge. At faster speeds, it is also present at the 3 to 4 shift. Both in Manual and in Drive.

Has any else had this problem ? and have you solved it ? Thanks.
