I believe that there is a switch that will only allow you to take it out of
OD when you have low vaccum. The reason is that when you take it out of OD
the engine RPMs will have to raise to match the speed of the tranny in a
lower gear. Otherwise, you would have a bit of a load on the tranny to raise
the RPM of the engine to match. Or I could be completely wrong. The later
model LH types do not require this

I have some questions about how the electrical system works in an early
overdrive. when I flip the OD switch on, the car immediately goes into
overdrive if I'm in 3rd or 4th gears. When I flip the OD switch off, the
OD
will not disengage unless I am accelerating. Is this right? It seems like
it
should be the other way. By the way, I have all of the correct electrical
components: dasboard switch, relay, vacuum switch, etc.
Thanks
