Talked to Russel at Sound German Auto about the shifter control for a 8HP-70 tranmission. He said as long as the trans comes out of a Charger or Challenger (not a Ram) it can be controlled with a dial shifter or a floor shifter. The floor shifter allows for the manual shift option +D- , but the +D- control can also be done with many other types of switches.I asked about using steering wheel switches like those on the back side of a Jeep Liberty steering wheel. The operation would be similar to paddle shifters. So based on that logic the old dash mounted push button control could also work for the PRND trans functions.
