I could stay at 40 for very long but I did try 45 for several miles. It did not do it. But I also tried it at 65 and it did it again but it was going up a very low gradual grade. I bought the truck with 119,000 2 months ago and has done it since I got it. It doesn't have any problem shifting up or down. I do not know if the trans fluid and filter has ever been changed. Is the converter locking and unlocking a problem I should be worried about or somehow to check? Maybe it just could be me, being cautious since this is a new truck to me. I always heard that a bad converter shakes and vibrates while accelerating..
