Note in my picture that the converter shaft has the holes in the annular groove just behind the splines. I assume that means it's a later converter shaft or has been modified per the service counselor bulletin. Does that mean it should work regardless of which front pump is present as the fluid could enter the shaft either way?

Well, it took hours to scroll through the 241 pages. Whew. The only front pump pictures were the in place ones prior to removal and after reinstallation. No discussion regarding the difference between 55 and 56 shaft and pump.
I've attached a picture of the converter shaft. Can someone tell me if it's a 55 vs 56 part? I take it there's no way to tell what the front pump is without removal of the bell housing and pump.

Well, I pulled the torque converter apart since I had it out. The only thing I found is two of the adjacent large rings had the gaps separated by only an inch. I spread them apart but I don't believe that would prevent the clutch from working. The clutch friction plate has a little wear but not that much. The grooves are still visible, just not as deep as a new one. I can understand why he didn't bother replacing it.
His belief was that the failure was due to not replacing the friction plate, but I would expect at most that would cause a bit of slippage but there's nothing. The DD hydraulic pressure comes on at the port but absolutely nothing is felt. There's no engagement. The ports are clear at the clutch hub, but there's no visible passageway in the converter for the fluid to reach those ports specifically -- just the gap between the hollow shafts, I assume. The transmission is not out of the car. Not having an ultramatic apart before I'm not at all familiar with what is required to inspect the front pump and shaft part compatibility. (The only AT I've rebuilt before is a Ford AXOD).

Interesting. Thanks for the info. The transmission was rebuilt but I have no idea what specifically was done. If this part mismatch were to have occurred, would the DD hydraulic pressure on the side port of the transmission still kick on at governed speed with normal pressure? That test did pass.

That I'm aware of, but while I'll be checking the clutch friction plate (I have a new one, btw), that the piston isn't seized and the ring gaps are staggered, one thing I don't know is the hydraulic path to the piston. I'd like to blow it backwards to ensure it's not plugged with something. I assume I'll find a port behind the piston.

Got the converter removed. The center bore on the crank was rusty and they had rusted together. Now to disassemble and see if I can figure out why the direct drive clutch isn't working. I'm assuming I can just invert and remove the clutch side cover without tearing everything down through the turbines, then disassemble the clutch from the cover.

Converter is hanging on to the back of the engine. The mechanic says he's used prybars but was afraid to pry any harder for fear of damaging the flywheel.

The engine was removed from my '55 Patrician. This vehicle came with a rebuilt engine and trans but the direct drive clutch has not been working from day one. With a pressure gauge I confirmed the clutch hydraulic pressure was kicking on at governed speed but no actuation.
Anyway, while removing the engine it was discovered the converter to flywheel nuts were all loose. However, the real problem is the converter will not separate from the flywheel. It's still attached to the engine and prying on it won't dislodge it from the flywheel. Any ideas?

I've confirmed voltage is at the radio but no vibrator hum. It's a stock looking vibrator. Guess I'll be pulling the radio. I see there are two separate chassis.
