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... from 60 years + and mostly unsorted.

But surely someone else out there knows this stuff and can show you a 1956 Ultramatic shifter arm made for a senior Packard that was originally equipped from the factory with manual selector lever?


Here are two I found on ebay. Do either of these look correct?

1956 Packard Automatic Trans Outer Lever for Manual Control Valve, NOS, #6480732

1956 Packard Ultramatic Outer Manual Valve Lever 6480732 NOS


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.


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.
