Strange intermittent auto trans problem--65 classi

Well I'll get a chance to once I get it back together either later tonight or tomorrow.  I'll pull out the manual and read up on pressure test procedures.  I'm not sure if I've got the fittings to make it work with my gauge though.  Might require a trip to the parts store tomorrow.

But it would quit working if I came to a stop.  Once I shut the engine off, and let it sit for a couple of minutes, I could fire it up, engage drive, and drive off.  Soon as I would stop, nothing.  I'd have to shut the car off, let it sit, then restart.  Never encountered anything like it.

I'm not so sure. The valves control where the oil is going. Once the governor stops turning internal pressure is greatly reduced. That can let a valve release and take a few seconds to build pressure to get it open again.  The pressure regulator is also part of the valve body.

Hmm.... could be a sticky governor too. There is an oval access plate on the passenger side of the output shaft housing. Jack a rear tire up and put the trans in neutral. Take the plate off, then turn the tire until you see the top of the governor. There are two bolts holding it in. Take those out and pull the governor. It's simple, a spring and... well, I don't recall from memory. It will come off and go back in easy though. Pull it, clean it, then reinstall. Shouldn't take more than an hour or two total.

I'm not saying it can't be other issues. Leaking servo o-rings and tube o-rings are common. All those can be fixed without pulling the trans. Only if the pump or clutch pack o-rings (I seem to recall at least one...) are leaking does the trans have to be pulled apart. Most common internal leaks are the servo and/or tube o-rings. You can get a gasket/rubber/seals/rings kit from Northwest Transmission for $52. That has everything you need to replace all that, but the "less steel" kit is $73, master overhaul $87. Might want one of those for the little more $$$.

Governor doesn't cause that.   if the governor didn't work, It would not shift. It will have reverse, and 1st.

Well that was a waste of $40 in tranny fluid.  Now it won't move at all!  I think all that clutch material that was floating around in the fluid was just about the sum total of whats supposed to be on the clutches!  I pushed it into a longer-term parking spot until I can order a rebuild kit.  Again.
