[Healeys] tips on overdrive use

I just try to ease the strain on the unit by taking my foot off the gas when 
shifting into overdrive and giving it a little gas when coming out (actually 
my throttle switch takes care of that part).  This more closely matches O/D 
speed with O/D speed as it shifts.

I have had good luck driving my TR4A with OD for about ten years with no 
mechanical problems and 8 years in the Healey with no mechanical problems 
with the O/D (probably just jinxed myself).

I use the O/D all the time even when driving in town if speeds exceed 45-50 
or so because the 100 motor doesn't really feel very happy at higher revs, 
not just on long highway cruises.

Long ago when I was first driving British cars the owner of one of the parts 
shops I frequented said the cars were happier and more dependable 
mechanically if used regularly than if they sit.  I took the advice to heart 
for my cars including the o/d unit.  Don't know if it is right, but it is 
sure more fun than leaving it sitting in the garage.
