I will be attempting a trans swap and read the threads concerning a swap.

I want to try and retain push buttons....the catch is I can ignore park due to having rear disc brakes with integrated park that works! I have it all attached to the foot pedal of my 57 imperial.
2nd gear is also not of importance to me.

With that said is it easier and more do-able to make this swap work with push buttons? Any parts recommendations or recommendations in general?



I picked up a 1995 46RH with a starter, converter, hardware, and a cross member for $297 from a 1995 ram 1500. I also grabbed the shift linkage and kickdown cable. Took about 3.5 hours to remove it myself plus a lot of dirt at a junkyard here in SoCal.

Thanks for any advice

I wondered how many folks would offer up suggestions on this swap....apparently not a popular option.
In the past there have been some 'kits' to allow for using the PB drive on a 'normal' trans but they were never mainstream; perhaps due to cost?
If you know a good Mechanical Engineer in need of a convoluted project then report back on the process. I have tackled some odd-ball design projects but not sure there would ever be enough pay back for the hours involved in something like this.

What ever happened to Imperial Services and their 'kit'?

I dont know what happened to imperial services kit, would be nice if it were around still. I would think this would get a bit more attention since the torque converters for old torque flites don't exist. Some replacement parts just don't exist anymore so this swap isn't a terrible idea in my opinion. The initial investment is a pain in the rear (trans, torque converter, some wiring, making buttons work, drive shaft mods) but in the end you get modern over the counter parts and an overdrive.

Thanks for the response. I am sure I can get a 1 off to work.

I plan on doing this exact swap some day, I was fortunate enough to get the Imperial Services kit while they were still available. When I have some free time, I could draw the parts in CAD so people could duplicate the kit. There is a user on this site, think his user name is "PowerFlite", that has swapped OD trans into many FL cars. I'd check in with him, I believe his real name is Nathan.

I have a 1956 dodge with a 1970 Dodge 383 engine. The transmission is a A518 (46RH) out of a 1992
Dodge pickup. Rear member is a sure grip out of a 69 charger.
The 56 Dodge has only four push buttons. Neutral, Reverse, Drive and Low. I very much wanted to keep the original push button look in the car. Frist I tried to use the cable from the original two speed and hooked it up to the shift lever on the A518 but had little success. I wanted to be able to use Park in the new transmission and the conversion offered from Chrysler Imperial would not accomplish that. Also quite expensive.
I remembered from when I was a teenager my dad had a 1958 Edsel with an electric shift using pushbuttons in the middle of the steering wheel. I did some research and found a used shift motor on Craigslist that I purchased . The Edsel shifting assembly is call Teletouch The motor has 19 wires in the wiring harness. They control the shifting, the neutral switch , a lockout feature that won’t allow Park or Reverse to be selected when moving forward and controls for the backup up lights. ( I have a wiring diagram) The motor takes a special relay that has two contacts to allow the motor to run forwards and backwards. I found one in a local salvage yard

Also from the salvage yard I purchased transmission linkage from a dodge pickup that you would use on a column shift. I ran the linkage from the transmission to the firewall of the Dodge. I had to drill one hole in the frame to mount part of the linkage. I made a bracket for the shift motor and mounted the shift motor on the firewall. I then attached the shift linkage to the arm of the shift motor. To get the throw correct between the shift motor arm and the arm on the transmission I added a short extension to the motor arm. You can see it in the picture included.
The Edsel shift motor has the capability for five positions but the 56 Dodge only has four push buttons so I did not use the one for low. I modified the back of the pushbutton assembly by making a bracket to hold four micro switches. I mounted the switches so that when a push button is pressed the micro switch is actuated and sends a signal to the shift motor to shift the transmission to the correct position. ( Picture included)
The original pushbuttons as I have stated were Neutral , Reverse , Drive and Low. I am changing the buttons to read Park ,Neutral ,Reverse and Drive. (Switched Low for Park). I went to a trophy shop and they are making new letters on plastic. I will grind off the letters on the original pushbuttons and glued the new letters in place.
Anyone that is interested in making this conversion can e-mail me at rmccombs46@bellsouth.net
