Lined the fluid sleeve up with the governor. Torqued the lot down and set the reverse lockout piston stop to 1/2".

Took the carburetor off, fitted the heat shield and then put it all back together again.

The passenger lock had stopped working. Found out why, the anti rattle O-ring had broken. As such the button was sitting too far out and the lock wasn't engaging.

Back down and all together. Just needs filling with transmission fluid.

I had time to sit and reflect on the automatic gearbox comments and such, and reading the "what was on your street when you grew up?" thread made me reflect on why I do things the way I do.
Family history has a fair bit to do with it. Going back as far as I knew people personally- my grandfather was a navy engineer. He served on the submarines and worked his way up through the ranks and ended up as chief of the chief engineers. He never talked about it much, though.
Learned recently that he was part of the king's funeral procession, he was first line behind the carriage; he's forever immortalized in the Pathé film, which makes me proud.
My father moved about a lot with him as a result and later on my father joined the air force. He was stationed in Rhodesia (shows you how long ago that was...!) and served doing aircraft maintenance, Mosquitos, Twin Otters and the like. He was airframe.
Once he left there he was invited to become an instructor at RAF Halton in Aylesbury. Look up the 101st entry and you can see him in the mass of faces. They recently got in touch with him and suggested he should get the service medal for being there. He was sceptical bit I said go for it, jump at the chance. After leaving Halton, where he met my mother who was in the WAAF he got a job at South Bristol College lecturing hydraulic and pneumatic automation systems. I remember going there occasionally and being shown the pneumatic systems, building things with it. He still lectures aircraft automation systems at the college in Barry, South Wales.
We never had much money so there was very much an attitude of make do and mend in our household. Dad worked during the week, my mother worked the weekend. My father's perspective on the car was if you didn't fix it on Sunday night, you were riding your bike or walking to work on Monday morning...
So, I learned how to take things apart, how to fix things, to learn how they worked and about general engineering principles and norms.
I guess really I'm happy taking the oily bits apart and learning how they work so I can fix them- I look at it this way, they made a service manual so people, not magicians or wizards- could fix them when they broke.

So that's really where I stand with it. Old junk can be fun.

Just went shopping. Not bad for $21, 12 quarts (3 gallons).

Went for a drive last night after filling the gearbox up and occasionally it'll drive very well like that, other times it does stupid things; the one thing it did that made me stop and think was engaging the parking pawl going into reverse.
That should only happen when there's no oil pressure.

So, my next port of call is the pressure regulator, I'll pull that out and see if it's sticking. I'm hoping that's it.

The new governor wasn't money wasted, the old one is worn out, the new one moves so much better.

I don't know if this is at all relevant but we had an Audi auto box rebuilt which then went on to be an utter pig and wouldn't change. On the way down to the auctions to off load it it gave a lurch then drove absolutely impeccably and stayed that way before being successfully retailed.
Obviously there must have been some dirt particles somewhere that shifted.
Do you have a car auction locally?

Pulled the pressure regulator and cleaned it.

It's still being sticky from first gear on occasion and the 4-3 isn't operating so I'm going to pull it completely apart, drop the pan, take all the valves out and clean it all down again.

Great fun

Went out for a drive tonight to see if things would free up. Not really, but it was nice to drive about, despite the turn signal flasher relay stopping working halfway home.

Regular 45 Watt sealed beams, federal spec. They aren't bad when they're got halfway decent wiring feeding them.
