I disagree.  That's exactly why there is a _clutch_ in the overdrive instead
of simply sliding gears like the transmission uses.  The clutch slips during
the adaptation period to limit the shock applied to other components.

And indeed that is a common problem on the TR6, even with slow shifting (or
no) overdrive.

Indeed.  Lots less inertia, too.
