 The powershift transmission sounds at times like it is grinding aluminum cans in the transmission. Usually happens at slow speeds , turning or uphill. From stops or in turns, the trans lurches. On hard acceleration or highway, there are no issues.Have gone many rounds with ford dealer, corporate etc. All say this is normal for this trans. The powershift is dry clutch technology designed to hit high mileage. It delivers the goods on mileage, but the trans grinds louder than my 83 AMF Harley.Very disappointed, This is unacceptable to me. I'll give up a mpg or two for a smooth quiet hydraulic transmission.Took a loss on it and traded it for another manufacturers vehicle.
