I just got the tranny and overdrive back into my '56 BN-2 and it is running
smoooth!
But I still have this weird thing going on with the overdrive. Basically the
way it is operating is that when you have the dash switch in the off
position, it runs without jumping into overdrive. Well that is normal, but
once you flip the switch it will go into overdrive at the appropriate times
only in third and fourth and it comes out of overdrive in any other gear.
And that is normal as well.
The problem is that if you put the switch in the normal position after it
has been in the overdrive position, the system will not revert back to the
"never go into overdrive situation". What I mean is that it will continue to
shift into overdrive at the appropriate times in third and fourth even
though the switch is in the normal position. The only way to get it to
revert back to the "never go into overdrive (or normal)" operation is to
turn off the key. I've even tried this while driving down the street.
Turning off the power and then turning it on and starting the engine and the
overdrive then stays out.
Now this may all be the way its supposed to be! I'm not sure. I can see
where it would be kind of a safety thing where hitting the switch
accidentally might cause a high revving situation if this didn't do what its
doing.
I've checked my wiring against the diagram several times. This is a BN-2 so
it has the later design and all is correct. I'm scrutinizing the schematic
and I guess myself I would have designed it a little differently having the
dash switch the gas pedal position and the gear switch all in series to have
the effect I'm expecting and its kinda like that but not exactly and that
could be why its doing this weird thing.
But then may be its supposed to be like that.
Anyway I had a great ride the other morning just going around my block about
a hundred times checking it out. Finally the power train is running smooth
and I was relaxed enough to enjoy all the sensations of driving my fully
rebuilt Healey.
