Controlling a GM Turbo Hydromatic with a Cord Shifter

BILL

THE FULL SIZE CORD REPLICAS BUILT BY SOUTHEASTERN HAD THE SAME DRIVE TRAIN YOU ARE RUNNING AND ONE I LOOKED AT HAD A CORD LIKE SHIFTER, IT WAS JUST SEQUENTIAL LIKE THE AUTOMATIC PATTERN. IT USED AN ELECTRIC SERVO TO SHIFT THE TRANNY. PERHAPS IF YOU COULD FIND ONE OF THESE SERVOS, YOU COULD ADAPT IT TO THE ELECTRIC IMPULSES GENERATED BY THE CORD SHIFT MECHANISM. VERY CAREFULLY! IT WOULD BE MY FEELING THAT USING REVESE AS PARK WOULD BE BEST SO AS TO MINIMIZE ANY CHANCE OF SHIFTING INTO PARK WHILE MOVING, BUT OBVIOUSLY THIS CREATES A PERPLEXING SITUATION FOR ANY DRIVER UNFAMILIAR WITH THE CAR. GOOD LUCK.

Until I put the original engine and transmission back into my 810 Cabriolet, I am going to have to make do with what I have.

OLDS 455 W-88 ENGINE
GM TURBO HYDROMATIC 400 TRANSMISSION

I now have a Cord Steering column and fully re-wired shifter. I want to make the Cord shifter control the Turbo Hydromatic transmission.

Do any of you know of any after-market electronic interfaces? Someone said MOON makes one, but I have yet to locate it. Any ideas out there?

I don't want to reinvent the wheel. If some company has an electronic interface, then it should not be all that hard to connect a Cord shifter to it.
