This model in fact had differing discs early on then same discs after a certain serial number. ( in the same year) trans didn't change. Nothing else relevant changed. In fact I'm not aware I ever noticed a slowing down - down shift. I'll have to think about that while driving. It seems to not down shift until you request acceleration, so not a slow down type downshift as you mention. What is a nudge? and again, what do you consider to be offset type and what applications were they spec'd for?

If you notice the tripod flange, it has sunken holes to receive the protrusions on the flex disc, Thats what I called sunken bosses of the flange.
I dont know the exact cut off date of the "soft" flex disc for the W126 - but it was somewhere in the mid80s. Before that all cars had the same front and rear disc.
The nudge I mention is when you are slowing down to a stop - you will feel a gentle nudge as the transmission shifts to 2nd or 1st gear (dependant on your car) - The soft disc was to eliminate that "lash" feeling from the driveline. Its very subtle but its there.
If you own a later electronic transmission car, you will definitely feel that downshift to 1st as you slow down to a stop. Thats the nudge I was mentioning.
