The instrument cluster will show the
current selected gear you are in.
In order to prevent the engine from
running at too low an RPM, which
may cause it to stall, the SST will
automatically make some downshifts
even if it has determined that you
have not downshifted in time.
Although the SST will make some
downshifts for you, it will still allow
you to downshift at any time as long
as the SST determines that the engine will not be damaged from
over-revving.
Engine damage may occur if excessive engine revving is held
without shifting.
