James,
I only have a couple of months of driving on my new OD and I really love it.
It transforms the car. Here are my comments.
>Questions:
> 1. When should I engage & disengage the overdrive?
You can treat your OD just like 5th gear on a modern 5-speed car. So when you
are accelerating up through the gears and you get to 60-65... and you would
normally look for a higher gear... just flip the switch. I engage the OD when
the engine RPM is around 3000 RPM and I am in cruise mode. I have not found a
use for the 2nd and 3rd OD modes other than you can stay in OD mode even when
you have to slow to accommodate slower traffic momentarily.

The A-Type is strong enough to be engaged at any time. The thing to watch out
for is disengaging into an over-rev situation on the engine

I treat the shift into and out OD mode like any other gear change and use a
little bit of clutch just like the change from 3rd to 4th. I am getting use
to it now and find the shifting sequence easy and natural.
