Couple of weeks ago my transmission started going haywire. Downshifting by itself at stoplights and then throwing every code except middle east launch codes. Not driveable. Towed to a local well established trans shop where I was told after diagnostic I needed a full trans rebuild. $4100. So when I picked it up, the owner told me how my axles were extremely difficult to rmove, a broken trans mount bolt etc and that when he test drove it after repair, he felt a slight shudder at initial acceleration from dead stop but that it was due to less than perfect axles and some other stuff I didn't grasp about teflon plates or?? Anyway I've been driving it for a few days, and it drives ok on freeway and it seems to shift smoothly thru all gears, but there is a random shudder at take off for a moment that goes away and does not happen every time. It is also evident in reverse, especially if a slight reverse uphill. If I go back to this guy, I'm expecting a finger pointing contest. Question to group is...does his explanation of worn axles make any sense as to the cause of the shudder, or is it a symptom of poor rebuild? Torque converter is supposedly new.
