Fred, the solenoid will stay engaged when the switch is turned off until you 
accelerate beyond about 1? of pedal movement.  The bolts on the overdrive 
adjustment are 7/16 or a 1/4 British which are almost the same size.

While the subject of overdrives is being discussed, I have come across ongoing 
problems with the overdrive of my 66BJ8.

The overdrive is filled with 30 WT non-detergent oil and after running the 
engine, for about an hour, with all 4 corners on jack stands, the trans oil 
level is spot on the line between "low" and "high".

Now for the problems;

1.  The overdrive does not disengage when turned off.  The hole in the lever on 
the right side of the trans lines up with the hole in the case when the OD is 
activated.  

2.  When I turn the solenoid power off, the solenoid lever does not fall from 
the engaged position.  I suspect the lever may be pushed against the trans case 
and the friction does not allow the lever to drop down.  When I move the lever 
by hand, it is not loose, it requires some pressure to get it to move.  The 
solenoid does not have a problem lifting the lever when I apply power.

3.  I cannot get a wrench to fit the pinch bolt to release the lever from the 
valve operating shaft.  What size nut/bolt "should the pinch bolt be?

3.  The solenoid does not release when the dash or ignition switch is turned 
off, (checked with a volt meter).  What could still be sending power to the 
solenoid?  What electrical part should I check first and how?

I have been struggling with trying to resolve this OD problem on and off during 
the winter and as the weather is now getting nice, I would like to get this 
resolved.

Help!!!!
