Do you have a picture of what a 56 one looks like?

Sorry, but no pictures of the arms handy. But whoever robbed me in 2002 got a box full of the 1956 arms.
Somewhere I have old paper photos I took back in the 1970s of the two arms laying side-by-side. But where those photos are right now? Who knows? I have bins full of paper photos... thousands... from 60 years + and mostly unsorted. But surely someone else out there knows this stuff and can show you a final-spec 1956 Ultramatic shifter arm made for a senior Packard that was originally equipped from the factory with manual selector lever?

The lever in the photo resembles the revised 55 lever as shown in the illustration accompanying the report of the rod issue in Service Counselor Vol 30 #1. The lever in the parts book plate 33 identifies the trans as a 56 and typical of 55. It shows a slight curve to the lever. Being there is a different part number for 56 Leeedy is correct -- there is a difference in levers and for that I apologize for not paying more attention to the differences and catching that.
The question would be did the entire column and linkage get transferred from a 56 parts car to make the conversion or was it pieced together. If you have a 56 column then everything might have been transferred intact except for the lever which might be sitting on on of the other transmissions if an extra came with the car. If parts are intermixed then I would agree with Leeedy that it can be a problem to adjust things. With the change in angle between the revised 55 and the 56 levers appearing to be fairly small there might be enough adjustment to firmly get in all gear positions. Does the lever move in equal steps with a distinct detent felt at each gear position N,H,D,L,R when going from neutral to reverse and back again? Once you verify the trans is going into each selection completely you might be able to adjust the indicator to read properly by moving the clamp for the pointer which is under the rubber cover on the column. If you cannot get it to read properly then most likely an adjustment is at an extreme probably because of a mismatch in linkage.

Nope. The parts numbers may be somewhere from 1956–perhaps when they printed lists. But these are the 1955 style. Dead straight. The ones I used and remember vividly were curved, not straight–no matter what the parts books or part numbers might say. And I had a Packard engineer back in the 1970s tell me why they changed the design.

Yes, there is a distinct feel when moving the shifter through N,H,D,L,R. The indicator itself on the dash is only off by maybe half a indicator letter at max.

Maybe someone will be able to find a picture. The one on the car looks to have an inward curve towards the transmission if looking at it from the front of the car to the back. When looking at it from the side of the car it looks straight. I'm not sure if the column is a 55 or 56. How can you tell the difference? I have all of the factory push button parts. It might be easier to convert it back if I can't get it figured out this way.

Problem solved! Mr. Pushbutton is the King of the Thing!
There is really no substitute for doing it right. Putting your Packard back to the way the factory built it with Mr. Pushbutton's help is the best way to get rid of all the guessing and guesswork and bogus circumventions and wasted time and angst and headaches. Now you can make your Four Hundred and its Ultramatic reliably do what it was intended to do.
