I originally posted the information after reading the notice in the instructions that came with a rebuilt lockup torque converter. Flying Doug didn't believe it and measured his used bolts compared to new ones and found 0.010" stretch. I suppose you could grind a little off the bolts and reuse them once, but since I saw that warning, I've used new bolts every time.

I don't remember if the warning was only for lockup torque converters, but it might be even more (or only) critical with those. The bolts are too cheap to take a chance.
