Re: Packard Engine to GM Auto Transmission Adapters

As far as I know this has not been done yet and is a sticking point and barrier for many 56 owners who have wanted a conversion. The aftermarket actuators I am familiar with use solid state circuitry and microprocessors to control things so would not be very compatible with the old school switch and relay logic of the original buttons for anyone wanting to maintain the stock look. One poster said he had heard Bendtsen had or was working on something to be available for the PB trans conversion but I have never seen any more info as to what or even if that is fact.
To use the Packard actuator would need a new contact finger assy with fingers spaced for the GM sector layout and then figure out a mounting and linkage to the GM lever position. A poster mentioned a mid 90s or so Rolls Royce actuator will bolt right onto the GM case and since it was made for a GM trans layout is already configured with the correct spacing on its positions. That was something he was going to try but no idea if he did. Schematically it should be possible as the RR actuator uses something similar to "fingers" and operation is similar to the Packard actuator. Instead of buttons, the RR gearshift lever actuates microswitches to feed the signals to the RR equivalent of fingers to control built in relays inside the actuator so that operation is also essentially the same. The question would be if the RR actuator would fit the space available in the Packard frame.

Ideally I'd configure the wiring to work with the factory pushbutton panel.
