I would say yes to the first part as it sounds like a sensor or vacuum hose was left off or became loose. As to the transmission I would think it is possible, as a lot of work was done in the engine area, not out of the question cable was damaged, or something like that. Sounds way too suspicious. Hope others will chime in here, I am not an expert mechanic per say but have worked on all of my cars, and also had them worked on many times when I could not for various reasons. A lot of sloppy work out there, would suggest you get this guy to d/c his work. A lot of money spent here for sure.
