It's a 4-speed. By the way the O/D on the TriumphB IS a different model - A
type rather than J type from memory. For the Triumph, the thing about
roadspeeds below 30mph is actually in the manual somewhere. So it looks like
the O/D in the Healeys is different.B  I think the hydraulic pressure in my
BN2 O/D is a little low, because it is very influenced by oil viscosity. But
it works fine with 90 gearbox oil (never drops out when I need it) so I will
leave well alone.

Thanks to you both for the input

Is the 100 a 3 or 4 speed?.The 3 speed has a
speed switch that cuts out 
below 30mph (centrifugal mounted at the rear of
o/d unit. The 4 speed 
doesn't have this unit
