<div>Thanks, Paul. That is helpful. The problem still
exists however, in that the diagram of the relief valve in the manual does not
agree with the parts in my overdrive unit. The picture you attached is
like mine. My question is, if the relief valve were installed improperly,
would that cause the overdrive not to engage? Yesterday, I reversed the
plunger to get it in the correct alignment and reinstalled the entire
assembly. I drove it this morning, and it didn't seem to make any
difference - the overdrive still did not engage. Any additional
thoughts? Thanks.</div><div><br></div><div>Jack<br></div><div><br></div>

<div>OK, attached is a picture of the components as they were installed in my
oil pump. I have removed it, and after carefully examining the
assembly,
I think I can see why it is not working. I had the plunger (the item in
the middle in the attached picture) installed backwards. I had the long
end of the plunger going down into the pump body, so of course, the plunger
riding on the cam would not even contact the plunger going into the
body. When I turned the plunger around, the 2 plungers now come into
contact with each other, thus allowing the pump to work.</div>
<div><br></div>
<div>I'd still be interested in any comments you have (other than "what a
s***head"). Also, I'd like to get an exploded diagram of the unit in my
car. Thanks for any help you can give me.</div>
