I'm kind of afraid to use WD-40 - maybe I'll try some graphite dust.
I might sound like an ass but, why do you need to AFMA a TS-E lens? Isn't this a manual focusing lens?
I am sure it has a motor to focus with inside of it. It may be stuck on this one. I would suggest turning the focus ring back and forth quickly and applying some WD 40 to see if it will shake the motor loose.
Excellent idea, the graphite will work its way in better.
From what I read on other threads you might try putting the lens on a crop body and see if it will focus. I am not sure what the advantage is but I do know it is 1.6 times better at it.
