I guess you can always bring it up to them to see what they have to say, the worst they can do is say "no, we'll not look at it", maybe they will even give you their opinion tooThis discussion about the torque converter makes me wonder if my problem with hesitation isn't a problem with the TQ too. The hesitation started after the new transmission was replaced. (which fixed the shudder). When the TMC was re-flashed, the hesitation was ok for about 2600 miles but started again. Do you think it could be the T converter? They have had my car for a week now with no word what they have or have not found. I told them to keep as long as they needed to get it fixed. My state requires that you give them 4 tries to fix it, giving a notice of "final attempt" on the fourth try. This will be my third attempt.
