Dual Mass Flywheel
I went through two Dual Masses before someone suggested something different. If I remember right, everything inside the bell housing thing is off of the big block. Probably 100k miles on this one and no problem. The dual mass just can’t stand up to the Duramax. First failure was at the DOT station in NM and the second was at the US/Canadian customs border.
(Must be something of an authority thing.)
