Hi All,

I was wondering if anyone could help me please. My 1956 Patrician push button ultramatic was working fine and then i went to go into reverse and nothing. If i put it into drive, no problem, but sometimes if i put it into neutral it wants to go forward and if i put it into reverse it wants to go forward (sometimes) but if i put it in park, then netural, then reverse nothing. I hear the actuator selecting/clicking but nothing. I tried the trick with the jumper wire to drive to align it back up, nothing, i tried it for reverse as well and i had nothing for any gear, so i redid the pink wire and it was back to how it was, minus the reverse.

My thoughts are that the worm drive or selector has over hunted and now can not reach reverse. Is there a way to fix this without having to pull everything apart? Or am i completely off the mark?



Sounds to me like you very well could have bent contact "fingers" on your pushbutton actuator. So. The more you run it back & forth, the worse it will be. It won't get better on its own.

These assemblies are old and most are very tired. So... it is very possible on some 1956 Packards with pushbutton shift that the contact pie section can– and will– over-travel. Then you've got bent contact fingers... and a repair job on your hands (no pun intended).

TWO suggestions:

1.) Remove the small plate under the actuator housing. Look for any broken bits and see if things are tight. If not, be sure to properly position and tighten.

2.) OR remove the actuator assembly (some will say this is impossible, but it isn't) open it up and see what's going on inside.

Finally... why not simply contact the fellow known as "Mr. Pushbutton" and get to the bottom of things rather than guess? Mr. Pushbutton is the expert... the pro-from-Dover on these systems, repair and rebuild. I believe he has rebuilt systems on hand and ready to go.

Contact him through the Packard Club web site. I believe he is also on Facebook.

By the way... I have owned MANY of these Packards, over many, many years. A LOT of them. My own method for avoiding problems with the pushbutton shifters when they are old and worn (as most are) is as follows:
>>>>> shift NOT directly from PARK to DRIVE (or vice-versa) which invites over-travel. Rather, I go from PARK to NEUTRAL... THEN to DRIVE (or vice-versa). This reduces assembly travel to slow and small increments and thus reduces possibilities of over-travel.

Good practice to help longevity of service on these units.
