[QUOTE="twofazed, post: 1094786, member: 13626"] I had this problem, very hard downshifts on the highway. Went to dealer multiple times, they couldn't duplicate and said they found nothing each time. Finally I refused to pick up the truck until it was looked into further so they pulled the transmission. Turns out I had a casting defect on the torque converter. New one came from Germany or something and it too had the defect, a second one came, and now all is well. 50k miles on it since without issue! [/QUOTE]
