ok so i had a new motor put in my truck this past week at no cost to me because it was under an extended warranty (04 Screw 5.4) picked it up and just almost outta town (dealers 45 mins away from my house) and the transmission jerked really hard a few times on the downshift, it seemed like the torque converter was messed up but it wasnt doin it all the time. So i turned around took it back and continued to bitch after they had my truck for 23 straight days and now its on the 24th day. i read on another forum that after the computer was unplugged for an extended period of time everthign resets including the shift points and all that stuff.

SO.... i was wondering if anyone has had this issue or had an experience like this? thanks
