Atip from an Auto shop for adjusting the cable shift on the BW35 box that
was given to me

Drive the car till it is completely up to normal running temperature,aprox
10 miles.
on a flat road ,slow down slowly to a stop,as you do so the box should drop
into first gear  at approx 3-5 mph importantly with a slight thump.This
shows that the pressures in the box are arround the correct level.If there
is no perceivable change (thump) then the pressure is to low.If the change
is at a higher speed and very evident ,then the pressure is too
high.Lengthen the ammount of cable showing to reduce the pressure.
On the SD1  BW 65 box there is an indication of correct cable position
The instructions from Rover.:
remove air cleaner.With engine at  idle (750-850 ) actuate accelerator
linkage till idle speed just starts to rise .Check the gap between the
crimped stop and the end of the adjuster,It should be between 10 & 20 thou.
If the is a later SD1 with the 180 box ,the shifts are goven by a vacum
regulator.check the vacum hoses for leaks
