I replaced almost all of the 22+ year old vacuum/pressure lines, cleaned many contacts and sensors (engine speed sensor looked like one of those iron filing/magnet toys from days gone by) and things are running measurably smoother and stronger.  I even surprised a Corvette at a stoplight yesterday evening - at least through most of second gear.

Even their sales people swear they do not have the part and that there is a difference for the 3B engine.  I replaced the CMC in my silver car 4 or 5 years ago and AutohausAZ was the likely source.  They do show a CMC listing to fit a 200TQ with the MC engine:
