"good vehicle overall, but transmission does not always shift appropriately. just before 40 and 60 car tachometer goes up and down suddenly and feels as if the car is braking, on hills or on the thruway until you step on the gas and get it over that mark.
when taken to dealer to fix, said could recalibrate it which did help, but still does it. dealer unable to fix. is not always consistent response so hard to duplicate for them so they can experience the shifting stall before it goes into gear."
