problem solved.
Late January, I found a loose U-clamp with the nut and bolt just floating around in the belly pan. Of course, I was up there first thing in the morning and told them to make sure everything was tight and put back together. They said that a "Master Tech" looked into it.
He obviously did a great job besides the fact that he forgot to tighten the hose clamps and also explains why I didn't get a satisfaction survey.
Might also explain the persistant TC, I've been getting, among other problems.
